Just learned a lesson in physics the hard way.
Drove my car (Which is a piece of crap) down to my boss's place to let his dogs inside and close the back door.
It got there fine, but died while I was reversing out. It was on the road at the time, so I had to move it off the road, so I put it in neutral and started moving it down the hill, which turned out to not be the best idea. As we started moving onto the hill, it started gaining momentum, I tried to reach the shifter to move it into park (Hand brake is pretty much useless) but I couldn't, it kept rolling and it was dragging me along beside it, clutching onto the driver's side door.
It finally stopped when it banged into a thick fence post, sort of squishing me between the door and the car, Fence post was fine, car's a little banged up, though.
I'm mostly fine, other than feeling like idiot #1, and having a scraped up leg.
