IMHO, sure you'll get the bike through the auto-pay ETC booth, but then with the bored police who will be 500% more than any western country to keep artificial near full employment will be a tad rudely awoken by the presence of your bike and you'll have a bunch of blue and white Sanatanas in your mirrors.

The way it seems to work is, you approach a senior policeman or official in a good mood, say something nice about China or his lovely road then he gets on his radio to tell the other cops up and down the road that there is a laowei coming on a big bike and to let him pass as a one-off, because he is in a good mood, really very bored and also wants to show the subordinates that he has the power to break or bend the rules at his whim. Of course the next laowei could find this very same officer in a bad mood who may want to show his underlings how the law is enforced strictly with no exceptions.
