I've read so many reports about changing social skills following covid, as people weren't interacting with others and lost compassion, etc. People seem to be a lot more selfish and uncaring, and not just when it comes to driving! I do think covid is responsible, but I also think reality TV has a part to play, because so much of the focus is on looks / appearances and having it all. It's a very sad state of affairs, and I don't know what can be done to make people more caring.
On the subject of bad drivers, yesterday OH and I were in the car and watched a woman repeatedly drive right up the back of cars, slam the brakes on, wait whilst others overtook her, then pulling out and racing off at way over the speed limit, then repeating the same thing.
