So if I apply your argument to another form of transport, we should only be able to rent cars, not privately own them?
OK, not a completely fair comparison as they have a number plates to track them more easily. But if the police stop an e-scooter what's to stop them checking you have a valid licence regardless of whether it's rented or owned?
I accept that it's a trial and will hopefully lead to a complete change. I don't own an e-scooter but have some friends that commute to work on them.
I do also think they should change the speed limit of e-bikes to match North America, but that's another topic.
