I may not be chinese

but I'll try and throw in some of my own half assed answers

Do Chinese hate Japan?
Well, I've lived in Taiwan, and China, and been to Hong Kong and Singapore, and honestly, It's mostly people from Mainland (the younger ones I mean) that have an issue with Japan. Why? It's state sponsered (taught in schools/the media) I had students telling me they should go to war with Japan right now (well, this was a year and a half ago.. before all those protests) The Japanese are a convenient scapegoat for the government in China.
In Taiwan, most people really just don't care about the Japanese, they don't hate them, they don't worship them either. (Japan occupied Taiwan for about 50 years)
Re: do they love the government?
Some do, some don't. Myself, and several people I knew while living there came up with the theory that people (more so educated ones) see the disconnect between what is often said by the media and government, and what is real, and react in two ways, they either fanatically believe the government, or become very cynical about it. There isn't a lot of in between from what I saw.
Part of the problem is that in smaller places, the party still holds a lot of sway over every day life, and informers are still very much a part of everyday life. (IE students had to be careful what they said to me on campus)
mm and re: driving:
China has 1.9% of the worlds cars but accounts for 15% of global fatalities
but, then again the drivers are fine in Taiwan.
