I stopped at this intersection near my girlfriend's house... and watched 4 teenagers on bicycles and skateboards roll through the stop sign, at about the same time as I was punching the gas... I stopped about 5 feet of them just to prove my point that they shouldn't run stop signs.  I rolled down my window and pointed to the stop sign... attempting to illustrate my point.  They said "come out here and show us, we'll fucking kill you..."  I just drove away.
Sometimes I wish I could run down people like that.  
I don't think they understand how well a 4000lb SUV could flatten their asses.  Maybe they just need a lesson in physics.
