OK, joke time! What are bumper car rides called in China? Driving tests. Get it?
Oh man, that joke is so old it was before people looked down on racial stereotype jokes.
Wait, but Chinese people ARE terrible drivers.
Saying that Asian people do not drive well is a stereotype. You shouldn't consider all members of a race poor drivers when you've only seen a few examples. It's not correct to say that Asian people are bad drivers, there are many bad drivers of other races out on the road.
Now I say that you're thinking too much and have no clue on what you are talking about.
Have you been to China? Or even San Francisco? Statistics don't support your assertion.
