Last year late in the evening I saw a guy doing doughnuts in a target parking lot, he nearly lost control and barely avoided fishtailing into one of those 3'+ red concrete balls in front of the store. Made me wish I'd had a dash cam running.
When I was a kid my parents house was on a corner bordered by a curving, downhill street. My dad built a rock wall specifically to stop cars, they had 3 cars in the yard the first year they bought the house before the wall was built. Every year they lived there since at least 2-3 cars hit the wall (all year long) including a few driverless cars. If video surveillance had been easier back then I'd have quite the collection of video from 40+ cars hitting the wall. Amazingly, only 3 or so of the hits required significant repair to the wall.
