There’s a whole class of electric vehicles being held back by regulation.
Do you know that there is a reason for the regulations on light motorcycles, mopeds, mofas, Vespas, scooters and however you name them? It’s the number of fatal traffic accidents. And yes, there are probably over two dozens of these motorized vehicle classes which originally started with the idea of an “bicycle with a bit of motor” such as mopeds and mofas.
I really can’t see this in the traffic accident statistics. Yes, there are a lot of motorcycle accidents, but if you look deeper into them, those are in most cases “real” motorcycles and not those slower variants. And if you take a look at those eScooters, most accidents here are people driving those rental scooters while drunk. That’s a problem, but that’s also a problem you won’t solve by regulating the dude going to the train station in the morning.
It is very clear from statistics of traffic accidents between cars and pedestrians that risk of lethal injuries rises sharply with speed, even at speeds of 30 km/h. It does not make a difference whether a car crashes with 30 km\h into you, or you crash with 30 km/h into a car.
It is also very clear that riding light motorcycles is far more risky than riding a bike.
