...but what if it's a real asshole doing the merging?

You mean you're being a cunt and not letting them in?

This logic is just plain wrong... if you have a single lane x yards long (first scenario, merge early), then you told all the cars to spread into 2 lanes that were zippered and READY to merge into one lane...it would STILL BE X YARDS LONG! Traffic is still slow going and still x yards long, but in scenario 2 they all have a car lengths space in them.

The only reason scenario 2 is best is because it STOPS idiots from running down one side until they get to the front of a line that is NOT ZIPPERING. Thus now the first line has to stop before an idiot in the merging lane causes an accident waiting till the last minute.

If you ever think you will be able to maintain speed when merging busy lanes, you are deluding yourself.

So they are asking a country that elected chump to use proven facts to alter their driving behavior for the social good.
