I started backing up into a spot and saw their reverse lights so I stopped. Honked when I saw they were not stopping and threw it in drive and moved just in time. Another Camry Dent driver who’s blind and deaf I guess. I should have seen their lights earlier to prevent this but I was focused on the car in front of me and their lights were not on when I passed them. Definitely would not intentionally back into a spot next to someone trying to back out.
