Driving to pick up kids from school yesterday and this guy is going 25 in a 40 with no signs of speeding up in his brand new dually truck on a two-lane road by my house. Traffic is quickly backing up behind him with a ways to go before the next light. I'm 2nd in line. It's a wide road with a turn lane and no passing till the next light, far down the road. So after thinking about it for a while and watching the cars bunch up in my rear view I decide to pass him using the left turn lane. Totally safe pass but illegal. On my way by I honked and his head just about hit the roof of his truck I scared him so bad. I couldn't help but laugh. He was instantly furious and sped up to my bumper. I ignored him. There's about 1/2 mile before the next light and he's just stewing. We get to the light and I calmly my roll my window down and he rolls down his and I ask him how his nap was.
