NOT ADDRESSED TO ANY PARTICULAR READER OF THIS SITE: As part of our nation's Lane Courtesy Month celebration, Vox explains why you shouldn't drive slowly in the left lane:
Research shows that many traffic jams result from a surprisingly small number of slow cars obstructing traffic, with their effects rippling outward. A small buildup of cars that can't pass because someone is driving slowly in the left — right next to another car traveling slowly in the right — is the exact type of scenario that can start this cascade of traffic.
Now, some people counter that as long as they're going the speed limit, they don't have to move over — and by slowing down would-be speeders, they're making the roads safer.
Apart from the fact that in 44 states, simply going the speed limit doesn't permit drivers to travel in the left lane, this argument doesn't make a lot of sense based on research into how accidents occur.... research has generally shown that the strongest predictor of an accident isn't speeding, but variance from the average speed of traffic — and a car going five miles per hour slower than the surrounding traffic has a greater chance of causing an accident than one going five miles per hour faster than it.
