I remember as a kid riding to school one morning with my friend, Robby. We had just ridden over a big speed bump in the road. A truck coming in the same direction never slowed down at all and lost his muffler and tail pipe. The pipe part spun around in the road, right where we were, and Robby's back tire went over the edge of it. It must have been searing hot because it melted his tire and blew the tube right there on the spot. It was the weirdest thing... and the guy never stopped. (this was a speed bump put in front of the school to slow drivers down. )
As for deliberate, I've had bottles, food, curse words, middle fingers, whole hands reach out and hit me...
Ew ew ew ew, I hate it when people touch me...especially when passing me in a car....ew ew ew ewwww!!!
Or how about when you see the same car driving by you over...and over........and over? Creepy!
I used to have an open mind but my brains kept falling out.
