I have been there and it is not fun. When I was 15 I was crossing powell at about 53rd or so. I was crossing on one of those unmarked crosswalks without a light. The cars in the first lane had stopped for me. There was about a dozen cars behind it, so I couldn't see the other lane. I crossed knowing the cars in the first lane were waiting, trying to be curtious. I figured hey, if there is a car in the other lane, they will see 12 cars stopped, use logic, and come to the conclusion that some one was crossing the street. Nope.
I got hit by a car going 30 mph...wemt over the hood, somehow broke off the driver's side mirror, flipped and landed ass first on the back door leaving an add print before I bounced off hit the ground and somehow my body naturally tucked itself into a roll....I was told this by my friends who were crossing behind me, as I blacked out till after I hit the ground and rolled. I crawled to the side of the road.
The car stopped up ahead several feet. The driver gets out, a woman, looks at her car, looks at me, looks back at her car, looks at me and says I shit you not "Oh my God my car!"
I didn't break any bones somehow but I was bruised to fuck. And I'll tell you it is not fun. So @theprunetang I am sorry man, and that they drove off is even more so fucked. I did sue (my parents did on my behest) had a crappy lawyer, so I got my hospital bills paid, but that is about it.
Lets just say when I cross the street these days I don't fuck around.
