Why did they ban Motorcycles

[Nuhaus]

Why not just enforce the laws all the time, equally, on everyone?

Very good question. I have no idea, other than to guess it has to do with money and the massive population in this city.

One more point however, without consistent enforcement of city laws, it makes it very difficult to convince people to buy legally registered motos. Why should the 2 foreigners I saw last week driving loud 250 motards in Xujiahui bother with plates and licenses if the cop just pretends he cannot see them as they drive by? I was trying to pretend I couldn't see them either as my Chinese friends were making much less than respectful comments.
