It might be time to give up fixed riding….(possibly road cycling altogether)
How about just getting out of them sh*tty cities and overcrowded urban environments. (I'm talking in general, not just China.)
Traffic plain sucks and so does pedestrian dodging. Neither adds anything to the road cycling experience, unless you are getting race/training support and someone is handing you drinks from the car window.
Road cycling is not about dodging traffic, it's about pushing yourself hard, covering long distances or just getting out in the elements and environment. The cleaner the environment the better for road cycling. Maybe less ass for you to chase outside of the major metropolitan areas, but better quality of life.
At the least, do yourself a favor and go for a ride in a national park where there is minimal traffic. Or do a tour in the remote countryside. If you can't enjoy that, then yeah, go ahead and give up on road cycling.
