(a) Cars do obey traffic lights, at least in Shanghai and Beijing. Perhaps you're talking about 10 years ago, or in tier 2/3/4 cities.
(d) People do pay attention when they cross the road. You have to, because cars can turn right at a red light and, even though they're meant to yield to pedestrians, they don't.
(c) Creating an additional lane is rare in big cities.
I'm not saying this idea is workable, but the points you make don't seem the most pressing.
