Don't shoot me.I'm only the messenger.
I don't do it in moving traffic. but I "filter" slowly up non-moving traffic which was illegal here.
Lots of car drivers who're stuck get p'''off.Which I put down to jealousy"There goes another one" mentality.I had an SUV let my friend filter through on the outside lane on a jammed highway,then try to block the lane so I couldn't get through.It didn't work.Once when it was illegal two cops were there and I asked them if I could move to the head of the line they said no problem.
