But why would police look at a line of 100 cars going 65MPH and pull you out of the middle for going 51? Unless it’s for impeding traffic, which is a thing.
It’s not technically right, but you go with the flow of traffic and try not to stand out. Everyone technically breaks traffic laws, including the police. Unless you have exceptionally bad luck or you are traveling past the same speed trap or really strict cop, you likely will not receive any more tickets for 3MPH over. Stop signs though, I always come to a 100% complete stop, if the people behind me don’t like it too bad.
