This actually happened to me a few days ago.
While I was walking down the main street of a local town with my girlfriend, we had to cross the road to get to the comic book store. The cross walks force the drivers to yield to pedestrians. So, we press the button, the lights flash, people stop for us, we begin crossing. In an instant, this 60 or 70 year old woman came blazing down at 50 miles an hour and nearly blind sides me as I'm halfway through the crosswalk. She was inches away and I knew how lucky I was for being just a second early because she would've never seen the both of us soon enough to stop hard.
