Query: How fast can you drive on the Autobahn?
General speed limits in Germany are set by the federal government. All limits are multiples of 5 km/h. There are two default speed limits: 50 km/h (31 mph) inside built-up areas and 100 km/h (62 mph) outside built-up areas. While parts of the autobahns and many other freeway-style highways have posted limits up to 130 km/h (81 mph) based on accident experience, congestion and other factors, many rural sections have no general speed limit. The German Highway Code ("Straßenverkehrsordnung") section on speed begins with the requirement which may be rendered in English:
Any person driving a vehicle may only drive so fast that the car is under control. Speeds must be adapted to the road, traffic, visibility and weather conditions as well as the personal skills and characteristics of the vehicle and load.
This requirement applies to all roads, and is similar to the "reasonable speed" legal obligation levied in other nations.
, 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.

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.
The speed limit for most of the length of A6 is default 90 km/h (outside city limits). The section from Kaunas to Jonava has been upgraded to a dual carriageway with at-grade junctions and traffic-lights. The remaining sections are roads with one lane in each direction, leading through towns like Ukmergė, Utena and Zarasai.
It is generally acknowledged that the first really practical automobiles with petrol/gasoline-powered internal combustion engines were completed almost simultaneously by several German inventors working independently: Karl Benz built his first automobile in 1885 in Mannheim. Benz was granted a patent for his automobile on 29 January 1886, and began the first production of automobiles in 1888, after Bertha Benz, his wife, had proved – with the first long-distance trip in August 1888, from Mannheim to Pforzheim and back – that the horseless coach was absolutely suitable for daily use. Since 2008 a Bertha Benz Memorial Route commemorates this event.
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.
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).
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.
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 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 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.
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.
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 .
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.
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.
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:
Audi made a high-performance, 4.2-litre V8 engine (parts code prefix: 077, identification code: AEC) with a Bosch KE-Motronic ECU available as an option in the original European S4s, and made the decision to continue to do so with the S6, making a version of the 4.2 available as an optional upgrade over the 2.2-litre inline five-cylinder turbo. Unlike the five-cylinder turbocharged version, the V8-powered S6 was supplied with a four-speed automatic transmission as standard, but kept the quattro four wheel drive. A six-speed manual gearbox was also available as an option.
The Dutch Grand Prix was the last Grand Prix for German driver Stefan Bellof, who later died in the World Endurance Championship race at Spa at the high speed Eau Rouge corner. Bellof had won the 1984 World Endurance Championship driving for the factory Rothmans-Porsche team, but decided against driving for the factory in 1985 to concentrate on Formula One. He did however still drive in various WEC races for the private Brun team in a Porsche 956. Until his death, Bellof was considered one of the rising stars in racing and was rumored to have an offer to drive for Ferrari in 1986. The summer of 1985 was remembered as the saddest weeks for German motor sport, as both German Formula One drivers, Bellof and Manfred Winkelhock died within three weeks in WEC races. Winkelhock, who drove for the Skoal Bandit Formula 1 Team, died at Mosport Park in Canada when his Kremer Racing Porsche 962C crashed head on into the turn 2 wall at high speed. His co-driver for that race had been Brabham's Marc Surer.
As well as being fast in a straight line, F1 cars have outstanding cornering ability. Grand Prix cars can negotiate corners at significantly higher speeds than other racing cars because of the intense levels of grip and downforce. Cornering speed is so high that Formula One drivers have strength training routines just for the neck muscles. Former F1 driver Juan Pablo Montoya claimed to be able to perform 300 repetitions of with his neck.
High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, new lines in excess of and existing lines in excess of are widely considered to be high-speed, with some extending the definition to include lower speeds in areas for which these speeds still represent significant improvements. The first such system began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates a large turning radius in its design.
In an interview, Sebastian Schipper discussed his love for cars and how he wanted to create a film to show that of Germany's car culture. He stated he was not afraid to have the image of the car-fanatical director. Germany is known for its love of cars. It has the Autobahn which allows people with fast cars to use them to their full potential. Schipper states, "In the movie [cars have] to be something authentic - you realize that cars are more than going from point A to B. Cars are true" and further describes how certain cars define certain people. The cars that Brühl and Vogel drive represent who they are and that can be said about certain citizens in Germany as well. The most popular cars being the Audi and Porsche which is "typical German" according to Schipper.
Some cars with very powerful engines can reach speeds of well over . Major German car manufacturers, except Porsche, follow a "gentlemen's agreement" by electronically limiting the top speeds of their cars—with the exception of some top of the range models or engines—to . These limiters can be deactivated, so speeds up to might arise on the German autobahn, but due to other traffic, such speeds are generally not attainable except during certain times like between 10 p.m. and 6 a.m. or on Sundays (when trucks drivers have to rest by law). Furthermore, there are certain autobahn sections which are known for having light traffic, making such speeds attainable during most days (especially some of those located in Eastern Germany). Most unlimited sections of the autobahn are located outside densely populated areas.
Driving in Germany is regulated by the Straßenverkehrs-Ordnung ("road traffic regulations", abbreviated StVO). Enforcement on the federal Autobahnen is handled by each state's Highway Patrol ("Autobahnpolizei"), often using unmarked police cars and motorcycles and usually equipped with video cameras, thus allowing easier enforcement of laws such as tailgating. Notable laws include the following.
"", "", and "Burnout Dominator" use autobahn as one of their tracks. "Euro Truck Simulator", "German Truck Simulator", and "Euro Truck Simulator 2" features the Autobahn in its open world map. "Burnout 3: Takedown" named them as Alpine while "Burnout Dominator" divided them into two (Autobahn and Autobahn Loop).
"" also had a track that had the player drive across different sections of the autobahn. The entire game world of "" is set on the autobahn.
On "Gran Turismo 5" and "Gran Turismo 6", a trophy is awarded to those who have driven the same distance as the autobahn total length. In December 2010 video game developer Synetic GmbH and Conspiracy Entertainment released the title "Alarm für Cobra 11 – Die Autobahnpolizei" featuring real world racing and mission-based gameplay. It is taken from the popular German television series about a two-man team of "Autobahnpolizei" first set in Berlin then later in North Rhine-Westphalia.
Crash Time: Autobahn Pursuit (known in the United Kingdom as Crash Time and in the rest of Europe as Alarm für Cobra 11: Crash Time) is a mission-based driving game released for the PC in 2007 and Xbox 360 in 2008. It is based on the German television series "Alarm für Cobra 11 – Die Autobahnpolizei", and features several characters from the show working their way through criminal cases set in fictitious versions of the city streets of Cologne, and the autobahn in North Rhine Westphalia. The developers created a "Pathfinder" to ensure that the AI vehicles do not always follow the same path during a pursuit. It was not received well by critics, with graphics and plot being of concern. Four sequels have been released on Xbox 360 and through online content provider Steam.
