The problem with your example, is that punishing everyone with a license and registration, won't deter that kind of behaviour.

If it did, you'd never hear of people speeding, stunt driving, or driving dangerously in cars.

But I would also add that since bikes are stolen at an alarming rate, what would licensing and registering do to stop someone from joyriding on a stolen bike? Nothing, and they won't get caught, so it's no loss to them.

That said, those examples you give are infuriating. There are youtube channels where people "show off" with that kind of riding, even on motorcycles going over 200km/h. I'd love to say just enforce more, but people who do things dangerously on purpose won't stop because they once got a ticket for it.

Forcing people to go through additional barriers to get out of cars is a massive step backwards, and one that I can only imagine people who advocate for more cars would be behind.

That also ignores that fact that MANY people riding e-bikes are doing so because a traditional bike would be too physically difficult for them to ride. Think: elderly, people with disabilities, people with injuries, people hauling groceries or towing kids, people with hills to climb on their commute, etc. Barrier laws like what's being proposed discriminate against these people.

Why not go even further? Pedestrians should also register and pay for option of walking around. Also registration numbers on clothing would be appropriate because they do dumb things, like running, jumping or dancing, all in traffic 🤣

In my country every child (~12yrs) learns basics of road safety and navigation through traffic including recognizing traffic signs. Why don't you push for change of school system and want to throw bureaucracy around like crazy instead?
