Not all of them, obviously, but enough.
This is different from the Tesla drivers who think that their acceleration always lets them cut in front of people.
I've noticed that with taxis. In my city, taxi drivers have a reputation for driving like arseholes. I thought this too, but I started paying more attention and I realised that the vast majority of taxi drivers were driving entirely unremarkably. Before when I saw something which confirmed a prejudice, I thought it was more evidence in favour of that prejudice; now I realise that it was the Texas sharpshooter fallacy all along.
It seems to be true for just about every prejudice I've ever been told about. BMW drivers use their indicators just as often as anyone else. Owners of cheap Toyotas are just as likely to drive unreasonably fast as owners of high powered sports cars.
Maybe there's something about people who are first adopters of "environmentally friendly" cars feeling a sense of moral license, https://en.wikipedia.org/wiki/Self-licensing, and end up being less conscientious on the road as a result.
Or maybe the rest of us just notice these bad drivers more because the cars stick out on the road as new and unusual.
Or maybe the drivers tend to just be rich, distracted assholes.
