Jackwagons on two wheels will (usually) only hurt themselves. Let them go and say a quick prayer for their family.
Jackwagons on four wheels scare me. Had one the other day try to run my off the road; 27th street in Moore. Idiot merged in then decided to occupy the lane I was in. Had to mash the brakes to avoid becoming road pizza, then sped up/rode around him and yelled at him. At the next light he said "what is the problem" or some such crap. I said "you damn near ran me over". He mumbled some kind of apology but I rode off, not wanting to say something ugly.
I'm really tired of hearing drivers tell me they are sorry, that they didn't see me.
