No I am not being sarcastic, why does someone insist on maintaining 150 feet of distance in bumper to bumper to traffic. Then you get stuck while everyone behind you gets into one of the next lanes, pass you by, while slow-poke who can’t keep up with traffic has 10 cars slip into the gap, to which he/she figures they still need to maintain the gap and slow up even more.
I don’t like people who speed up to prevent changing lanes either.
However this is a judgement call. If see a potential slow driver wanting to get into my lane which is moving, I do not slow up to let them change into my lane. If it looks like someone who is going to be fast and aggressive, and will force me to slow down, then I’ll actually slow up a tad to let them in.
