One time when I was living in Shanghai, I accidentally took the train to the wrong airport and had to take a cab to the other one. The cabbie was driving on the highway right at the speed limit, and I was worried I wouldn’t make my flight. I asked him if he could rush a bit, but he replied that he would not speed because 100% he would get a ticket.

It only doesn’t work if the system is half assed. But I agree that in low speed pedestrian areas, the built form is a better solution, but knowing you will get caught is also effective (if you accept the privacy tradeoffs).

It is effective if there are cameras everywhere, meaning you are tracked and spied on everywhere you go.

I'd prefer we spend a bit more on the road infrastructure than live in a surveillance hell.
