Most of the developed world has radar cameras that take a picture of your car and license plate if you go over the speed limit (plus a margin of error). Sometimes even if you pass a red light. No cops having to "fear for their lives" at random traffic stops, no inconvenienced/dead drivers. Just a flash to let you know you screwed up and eventually the person the car is registered to (and who is therefore liable) receives a letter with a pretty picture and a fine.
I live in a major metropolitan city in the US. I am somehow always surprised whenever I see a car driving around with no license plates. It’s very common. I see one almost every day.
Yep. I drove around in a VW van for several years without plates or registration. (I was extremely poor then.) The other trick was, but it no longer works as much, to leave dealer plates on vehicles and never register them... this loophole has been closed in most US states by requiring registration with dealer vehicle sale. Already, it was often required for the new owner to register a vehicle integrated as part of a private party sale.
