Yes, I agree with you, from the little experience I have, these thingies are very often (not in themselves, but due to the way they are driven, everywhere and without respecting any rule) dangerous and a ban might not be a bad thing, but Paris at least made (skewed as it might be) the referendum. In Florence (Italy) the mayor attempted in 2021 to make the helmet mandatory for e-scooters (besides geofencing and limiting them in some zones to 6 km/h), but it was deemed like an excess of power by the relevant court. But, starting probably end of 2023, the helmet will be mandatory in all Italy for both private and shared e-scooters (besides other new rules for parking, a license plate, insurance, lights, turn indicators, use of high visibility vest at night). The renting companies won't have any trouble (besides the costs) to modify the scooters to comply but very likely the need for the helmet will make the whole thing fade away (IMHO). AFAIK the renting companies (some of which already introduced helmets, on a voluntary basis) have a lot of troubles with stolen or damaged ones. Besides, I don't think many people will happily put on their heads helmets used by someone else (without proper cleaning/sanitizing) and/or at the first few (not so improbable) cases of lice or similar there will be some new (sanitary) rules implemented, making sanitizing between rents mandatory. And - even for the private ones - the need for the helmet, registering to get a license plate, adding the lights, etc. and the need for insurance will likely cut down the usage.
