Actually the problem of inexperienced drivers isn't so hard - and governments here (and probably elsewhere) are making it worse by only allowing registered share- scheme scooters to be used on footpaths etc., when clearly private owners are more likely to be experienced. It would surely make more sense to require a basic sort of license to ride e-scooters on footpaths or roads, but honestly I think the public just need time to adapt - there were outcries over cars when they first started appearing widely on public roads (justifiably too, as they were pretty deadly).
