CMV: When driving on the highway, it is much safer to pass on the right, than to tailgate until the person in front of you moves over (USA).

Following too closely is one of the most dangerous things you can do when traveling on the highway, and there is never an excuse for tailgaing in *any* driving situation, ever.

If someone is going slower than you in the left-hand (passing) lane, it's much safer to pass them on the right hand side, than to follow them closely to try and force them to move over. If passing on the right is not an option, you should wait patiently until a passing opportunity presents itself.

If someone is already traveling over the speed limit, and you choose to tailgate them because they aren't going as fast as you would like, you are an overly aggressive driver posing a dangerous risk to everyone on the road.

While it's true that, legally, the left lane should only be used for passing, this is not realistically what the lane is used for. Arguments from a legal perspective will not sway my view.

It might be a viable option from an individual's standpoint, but passing on the right is much worse for entire driver community.

1. It "promotes"  slow driving in the left lane. If passing on the right becomes acceptable, the slow driver is no longer holding up the entire highway anymore, so there's less initiative for him to move.

2. It "promotes" staying on the left lane. If all the passing is done on the left, merging back into right lane is trivial, because the one merging is always faster than all the cars already in the right lane. If one can be overtaken on the right, merging back becomes slightly more difficult and dangerous. (Yes, you have to check the mirrors in both cases, but in the first case it is only to be completely sure, while in the second one actually has to be cautious about faster vehicles)

3. It destorts speed gradient on the multiple-laned highways. Let's assume that ideal speeds for three laned highway are 80-65-50 mph. The speed difference between adjanect cars is 15 mph. If you used the middle lane to overtake, you are probably doing around 80, which makes speed difference between you and the far right lane 30 mph, thus preventing the far right lane to safely merge into center lane to overtake.

4. Tailgating is not as dangerous as passing on the right. When you tailgate, there is only one type of accident to expect: rear ending a car in front. The closer the cars drive, the less speed difference there is. Even if the first car slams on the brakes, the speed difference at the moment of collision will be very small thus the accident will not be that dangerous. When passing on the right, speed differences are greater (see point 3.) and the impact is going to be much more severe, with geater chances of immediate injury as well as greater chance for completely loosing control. When overtaking on the right, other types of collisions are more likely to occour too (sideways, police-like PIT manouver chrash...)

Btw, does flashing high beams or using left indicator while driving behing a car not work in the USA?
