Not me, but I recall several months ago a new owner (had only had the car a day or two, I think) posted about a car pulling out in front of her from a parking lot while they were on a city street and the car braked strongly well before she got to the brake she thought the car prevented a collision. She even thought the car steered itself away from the other car but I posted saying the Model S firmware doesn't do that...yet.
Sorry I can't find the post I'm referring to, but am very sure I have described it reasonably accurately.
