I don't get this labelling of Audi owners as being bad drivers. There are a lot of shit drivers out there, and they seem to drive a whole lot of different cars. That said, I'm always wary of Range Rover drivers, who are either rich people who think they own the road, or women who can't handle the size of their own car.
Personally, I've had an Audi for ten years, and I love it. It's easily the best car I've ever owned.
