Traffic entering from the side roads just drive onto the main road making traffic on the main road to either brake hard or change lanes using the horn but strangely enough the traffic does flow quite well and we never saw a crash.
I cannot find statistics right now, but from memory China's human road kill inches toward 100,000 a year.
I know with 1 billion plus you have plenty spares and percentage doesn't look too bad, but still quite a few burials if you ask me.
Edit:
Not exactly what I've seen before and not as bad and 'estimate' only (whatever it means)
