Query: What's the speed limit on the autobahn?
One distinguishing characteristic between German "Bundesstraßen" and "Autobahnen" is that there usually is a general 100 km/h (62 mph) speed limit on federal highways out of built-up areas, as opposed to the merely advisory speed limit ("Richtgeschwindigkeit") of 130 km/h (83 mph) in unmarked sections of the autobahns. However, a number of "Bundesstraßen" have been extended as expressways (dual carriageways) (colloquially called "Yellow Autobahns"). Many of these have speed limits of usually 100–120 km/h, others have only an advisory speed limit like autobahns. Most sections of the federal highways are only single carriageway with one lane for each direction and no hard shoulder pull-out area.
Top speeds are in practice limited by the longest straight at the track and by the need to balance the car's aerodynamic configuration between high straight line speed (low aerodynamic drag) and high cornering speed (high downforce) to achieve the fastest lap time. During the 2006 season, the top speeds of Formula 1 cars were a little over 300 km/h (185 mph) at high-downforce tracks such as Albert Park, Australia and Sepang, Malaysia. These speeds were down by some from the 2005 speeds, and from the 2004 speeds, due to the recent performance restrictions (see below). On low-downforce circuits greater top speeds were registered: at Gilles-Villeneuve (Canada) 325 km/h (203 mph), at Indianapolis (USA) 335 km/h (210 mph), and at Monza (Italy) 360 km/h (225 mph). In testing one month prior to the 2005 Italian Grand Prix, Juan Pablo Montoya of the McLaren-Mercedes F1 team recorded a record top speed of 372.6 km/h (231.5 mph), which got officially recognised by the FIA as the fastest speed ever achieved by an F1 car, even though it was not set during an officially sanctioned session during a race weekend. In the 2005 Italian GP Kimi Räikkönen of McLaren-Mercedes was recorded at 370.1 km/h (229.9 mph). This record was broken at the 2016 Mexican Grand Prix by Williams driver Valtteri Bottas, whose top speed in race conditions was 372.54 km/h (231.48 mph). However, even though this information was shown in FIA's official monitors, the FIA is yet to accept it as an official record. Bottas had previously set an even higher record top speed during qualifying for the 2016 European Grand Prix, recording a speed of 378.035 km/h (234.9 mph), albeit through the use of slipstream drafting. This top speed is yet to be confirmed by any official method as currently the only source of this information is the Williams team's Twitter post, while the FIA's official speed trap data measured Bottas's speed at 366.1 kmh in that instance. At the moment Montoya's speed of 372.6 kmh (231.5 mph) is still regarded as the official record, even though it was not set during a sanctioned session.
The game sets on Germany's highway named Autobahn (Approximately 40 km (25 miles) on the game). The game supports a gaming wheel for it to be more enjoyable and a third-person view or to first-person view. There are 40 missions in the game and free play mode is available. Players can also explore the world in foot and can manually open the vehicle's door. There are male and female characters on the game. There is also realistic radio communications and day and night cycle on the game.
Two sections between Llanddulas (Junction 23) to Conwy (Junction 17) are signed as a 70 mph (110 km/h) speed limit because they are classed as non-motorway special roads. Unlike other sections of the A55 that have National Speed Limit (NSL) signage and are accessible to all motor vehicles, motorway-style restrictions (although the A55 is not a motorway) apply on these stretches of road (e.g. no pedestrians, learner drivers, farm vehicles etc). As the section is not part of the UK motorway network, or classed as an all-purpose road (public right of way), the National Speed Limit does not apply so 70 mph (110 km/h) signs (the maximum speed permitted on UK roads) are used instead.
The original speed limit on the M50 was 70 mph (112 km/h). The Southern Cross Route from J12-J13 was given a lower limit of 60 mph (96 km/h), due to its more undulating, twisting route. The route from J3-J13 was changed to 100 km/h after the Republic of Ireland's speed limits became metric in 2005, while the Southeastern Motorway section (J13-J17) became 120 km/h. The Airport Motorway-Port Tunnel section of the route from J1-J3 has a speed limit of 80 km/h due to the closely packed junctions and heavy volume of weaving traffic.
Acceleration from a standstill to takes 5.1 seconds for the saloon with manual gearbox, the Avant one tenth of a second slower at 5.2 seconds. The same dash to 100 km/h in the saloon with S tronic takes 5.3 seconds, and the Avant at 5.4 seconds. The top speed is electronically limited to . However, a comparison in the American automotive magazine "Road & Track" showed the sprint from 0 to 60 mph in only 4.5 seconds for the 6-speed manual transmission. With figures like these, the B8 S4 accelerates more quickly than its V8-engined predecessors. Audi of America claims that the version of the S4 achieves 28 highway miles per gallon, and a 0 to acceleration time of 4.9 seconds with the manual transmission and 5.1 seconds with the S tronic. Fuel consumption is rated at a combined . Therefore, the B8 S4, unlike the V8-powered B6/7 models, avoids the US gas guzzler tax. The B8 S4's 3.0 TFSI engine also gets only 1 m.p.g. less than the base 2.0 TFSI engine. This is one of the most important reasons for Audi to downsize their engines, while keeping the output equivalent better, by using forced-induction such as supercharging or turbocharging.
After acknowledging the warning signal the train has to stay below the braking curve (German "Bremskurve") - fast trains may travel up to 165 km/h and they must reduce the speed to below 85 km/h after 23 seconds. Note that the operation of high speed trains beyond 165 km/h is not based on visual wayside signals or PZB inductors (using LZB or European Train Control System cab-signalling instead in Germany).
The large downforce allows an F1 car to corner at very high speeds. As an example of the extreme cornering speeds; the Blanchimont and Eau Rouge corners at Spa-Francorchamps are taken flat-out at above , whereas the race-spec touring cars can only do so at 150–160 km/h (note that lateral force increases with the square of the speed). A newer and perhaps even more extreme example is the Turn 8 at the Istanbul Park circuit, a 190° relatively tight 4-apex corner, in which the cars maintain speeds between (in 2006) and experience between 4.5 "G's" and 5.5 "G's" for 7 seconds—the longest sustained hard cornering in Formula 1.
, Switzerland has no high-speed trains of its own yet. French TGV (TGV Lyria) and German ICE lines extend into Switzerland, but given the dense rail traffic, short distances between Swiss cities (because of the country's small size) and the often difficult terrain, they do not attain speeds higher than 200 km/h (ICE3) or 160 km/h (TGV, ICE1, ICE2). The fastest Swiss trains are the ICN tilting trains, operated by the Swiss Federal Railways since May 2000. They can reach higher speeds than conventional trains on the curve-intensive Swiss network, however the top speed of 200 km/h can only be reached on high-speed lines. The former Cisalpino consortium owned by the Swiss Federal Railways and Trenitalia used Pendolino tilting trains on two of its international lines. These trains are now operated by the Swiss Federal Railways and Trenitalia.

The prototype train of seven coaches and two locomotives was completed in August 1972 and by the autumn was running trials on the main line. The following year, high-speed testing was being undertaken on the "racing stretch" of the East Coast Main Line between York and Darlington. The set had been reduced to two power cars and five trailers, and there seems to have been a concerted attempt to see how fast the train would go. On 6 June 1973 131 mph was reached, and this maximum was raised as the days passed. By 12 June a world diesel speed record of was achieved. The drivers believed that 150 mph was possible but the BRB issued instructions for the high speed tests to cease. It was believed at the time that this was because the BRB wanted to promote the APT as the future of high speed rail travel in the UK.
The lyrics of the song are in German, the main refrain being "Wir fahren fahren fahren auf der Autobahn" (English: "We drive drive drive on the Autobahn"). The chorus was often mistaken for the English phrase "Fun fun fun on the Autobahn" and thought to be a reference to the 1964 Beach Boys' song "Fun, Fun, Fun". Band member Wolfgang Flür later commented:
Ralf Hütter has said that The Beach Boys were an influence on the band, and seemed more open to the interpretation of the chorus as a homage to their song.
Highway 2 has a wide range of traffic levels along its length. At the south end, the highway is a lightly travelled two lane road from the United States border to Fort Macleod. It then doubles to four lanes and volume progressively increases until De Winton north of Okotoks, but remains relatively light. Within Calgary, volume climbs exponentially on Deerfoot Trail through the southern suburbs of the city reaching nearly 170,000 vehicles per day at Memorial Drive near downtown, making that stretch of Highway 2 the busiest roadway in western Canada. Volume swiftly drops north of Beddington Trail in Calgary, but remains moderate on the Queen Elizabeth II Highway until Edmonton where it again increases to nearly 95,000 vehicles per day in the vicinity of Ellerslie Road. Whitemud Drive, Anthony Henday Drive, Yellowhead Trail, and St. Albert Trail are all busy expressways carrying large volumes of local traffic, especially at peak hours. North of St. Albert the drop in traffic is brisk, increasingly so after Morinville where the highway is no longer divided. Volume remains very light through most of the Peace Country before briefly exceeding 20,000 vehicles per day near the northern terminus in Grande Prairie.
Michigan International Speedway is a four-turn superspeedway that is long. Opened in 1960, the track's turns are banked at eighteen degrees, while the 3,600-foot-long front stretch, the location of the finish line, is banked at twelve degrees. The back stretch, has a five degree banking and is 2,242 feet long. Michigan International Speedway has a grandstand seating capacity of 84,000 people. Greg Biffle was the defending race winner after winning the race in 2012.
In Germany the driving licence is a governmental privilege given to those who request a licence for any of the categories they desire. It is required for every type of motorised vehicle with the exception of the smallest mopeds below 50 cm³, with a speed limit of 25 km/h, as well as motorised bicycles. (Even for these, there is a minimum age of 15 years and a small mandatory driving school course). 
The types of licences one may obtain are the same in all the European Economic Area. See European driving licence. 
The minimum age to obtain a driving licence is: 16 years for a restricted motorcycle up to 125 cm³, 17 years for a car with a legal guardian, 18 years for unrestricted car and 21 years for buses and cargo vehicles.
In 2007 the TGV was the world's fastest conventional scheduled train: one journey's average start-to-stop speed from Champagne-Ardenne Station to Lorraine Station is .
This record was surpassed on 26 December 2009 by the new Wuhan-Guangzhou High-Speed Railway in China where the fastest scheduled train covered at an average speed of . However, on 1 July 2011 in order to save energy and reduce operating costs the maximum speed of Chinese high-speed trains was reduced to 300 km/h, but services between Shijiazhuang and Zhengzhou East on the line still achieve in each direction in 2015. The revival of 350 km/h operation in 2017 on the Beijing–Shanghai high-speed railway allows for several services to complete the journey between Shanghai and Beijing in 4 hours and 24 min with an average speed of .
The inauguration of the Gatimaan Express by Railway Minister Mr. Suresh Prabhu on 5 April 2016 ushered the beginning of semi-high speed trains in India. The Gatimaan Express runs at the top speed of 160 km/hr from Delhi to Agra. With the great success of Gatimaan Express, the Indian Railways plans to start additional semi-high speed services along the Delhi - Bhopal / Chandigarh / Kanpur / Lucknow routes shortly. Railway minister Mr Sadananda Gowda mentioned in his Rail budget 2014 speech that the railways will start high speed trains at on 9 routes.Indian Railways is also testing to increase the speed of the Delhi-Mumbai Rajdhani express train. Dual locomotives are used for this purpose, one at each end. Thus accelerating and decelerating from both ends. Proposed increased speed will be 160kmph between Delhi-Mathura stretch and 130kmph for the remaining stretch. While Indian Railways is bringing bullet train from Japan, it is doing all possible things to cut down the cost for high speed rail operation by indigenously developing technologies.
In 2016 the CEO, Dirk Ahlborn, announced an agreement with the Slovakian government to perform feasibility studies regarding routes connecting Vienna, Austria to Bratislava, Slovakia, and Bratislava to Budapest, Hungary. Total costs for this project are estimated to be . The resulting annual system capacity is projected to be 10 million passengers. HTT announced in March 2016 that they would be using passive Inductrack systems for their titular Hyperloop. In 2018, however, the agreement expired.
One of the oldest existing purpose-built automobile racing circuits in the United States, still in use, is the 2.5-mile (4.02 km)-long Indianapolis Motor Speedway in Speedway, Indiana, built from March to August 1909, when it first opened for racing. It is the largest capacity sports venue of any variety worldwide, with a top capacity of some 257,000+ seated spectators. The oldest asphalt-paved oval track in the United States is Thompson Speedway Motorsports Park in Thompson, Connecticut, once known as the "Indianapolis of the East."

The GTA also consists number of King's Highways and supplemented by municipal expressways. One of the most principal highways in the GTA, Highway 401, is also the longest in Ontario and is also one of the busiest highways in the world. Notably, a segment of the highway passing through the GTA holds the distinction of being North America's busiest highway. The GTA is laced with a number of limited-access highways, including the 400-series highways. These include:
The Federal Road Research Institute ("Bundesanstalt für Straßenwesen") solicited information about speed regulations on autobahns from the sixteen States and reported the following, comparing the years 2006 and 2008:
Except at construction sites, the general speed limits, where they apply, are usually between and ; construction sites usually have a speed limit of but the limit may be as low as . In rare cases, sections may have limits of , or on one ramp . Certain stretches have lower speed limits during wet weather. Some areas have a speed limit of in order to reduce noise pollution during overnight hours (usually 10pm – 6am) or because of increased traffic during daytime (6am – 8pm).
Some limits were imposed to reduce pollution and noise. Limits can also be temporarily put into place through dynamic traffic guidance systems that display the according message. More than half of the total length of the German autobahn network has no speed limit, about one third has a permanent limit, and the remaining parts have a temporary or conditional limit.
In 2014, the conservative-liberal ruling coalition of Saxony confirmed its rejection of a general speed limit on autobahns, instead advocating dynamic traffic controls where appropriate. Between 2010 and 2014 in the State of Hesse, transportation ministers Dieter Posch and his successor Florian Rentsch, both members of the Free Democratic Party, removed or raised speed limits on several sections of autobahn following regular 5-year reviews of speed limit effectiveness; some sections just prior to the installation of Tarek Al-Wazir (Green Party) as Transportation Minister in January 2014 as part of an uneasy CDU-green coalition government. In 2015, the left-green coalition government of Thuringia declared that a general autobahn limit was a Federal matter; Thuringia would not unlaterally impose a general Statewide limit, although the Thuringian environmental minister had recommended a limit.
Just over half of the German autobahns have only an advisory speed limit (called in German "Richtgeschwindigkeit"), 15% have temporary speed limits due to weather or traffic conditions and 33% have permanent speed limits, according to 2008 estimates. The advisory speed limit applies to any road in Germany, regardless of its classification (e.g. Autobahn, Federal Highway, State Road etc.), outside of towns which is either a dual carriageway or features at least two lanes per direction unless there is another speedlimit posted, though it is less common for non-autobahn roads to be unrestricted. All other roads in Germany, again regardless of classification, outside of towns do have a general speed limit of 100 km/h, which is usually reduced to 80 km/h at Allée-streets (roeads bordered by trees or bushes on one or both sites). Travel speeds are not regularly monitored in Germany; however, a 2008 report noted that on the autobahn in Niemegk (between Leipzig and Berlin) "significantly more than 60% of road users exceed . More than 30% of motorists exceed ". Prior to German reunification in 1990, accident reduction programs in eastern German states were primarily focused on restrictive traffic regulation. Within two years after the opening, availability of high-powered vehicles and a 54% increase in motorized traffic led to a doubling of annual traffic deaths, despite "interim arrangements [which] involved the continuation of the speed limit of on autobahns and of outside cities. An extensive program of the four "E"s (enforcement, education, engineering, and emergency response) brought the number of traffic deaths back to pre-unification levels after a decade of effort while traffic regulations were conformed to western standards (e.g., freeway advisory limit, on other rural roads, and ).
There is a general speed limit of 80 km/h (50 mph) for trucks with a GVWR over 3,500 kg (7,716 lbs) and for vehicles with trailers. For vehicles with a GVWR of over 7,500 kg (16,534 lbs) the limit is set to 60 km/h (37 mph) except on autobahns (also 80 km/h). For coaches and cars with trailers the limit is increased to 100 km/h on autobahns (under certain requirements). Posted speed signs for trucks are not common, they can be seen on some dangerous curves or descents.
