That's my point. I think my mistake was not defining what a good and bad driver means. I don't mean safe, cautious, polite - I simply mean competent in moving the car where you want it to go. Drivers in America and even more so in China are aggressive, but they also can control their cars better because they have to! No one will let them in, they have to force their way. If someone in my country of origin drives at the speed limit, everyone will overtake him, even if it's dangerous and if it's physically impossible they will beep at him. In the UK if someone is driving 40 in a 60 zone there will be a long line of cars behind him. It used to boil my blood first couple of years. Now I'm patient like the rest.
Good point, this does boil down to what we mean by "good driver". If I hear that phrase in the UK, I take it to mean competent as well as safe, considerate, and knowledgeable. On the other hand if a sports person is a "good player" then it's more about their technical ability than their safety - "Cantona was a great player but boy did he foul a lot".
