The speed that traffic is going at any given time. Sometimes, it's twenty below the
speed limit, sometimes twenty plus over. If you go the speed limit while everyone else is going twenty over, you will get road
raged.
However, saying, "I was going with
the flow of traffic" to a cop is one way to guarantee getting a ticket.
Officer: I stopped you because you were doing 80 in a 55.
Driver: Offffficceerrr, I was just
going with the flow of traffic.
Officer: Does
the sign say 'Go with the flow of traffic'? No. It says 'Speed Limit 55'. Here's your ticket.
