I'm fine with a 100% self-driven/auto-piloted scooter/bike .. I'm sorry, but there are far too many uncoordinated fools out there without the slightest concept of newton's 2nd who are perpetually coming right up on my back for me to be cool with anything else (in an urban area at least).
Your comment works equally well for cars. Why not ban them until drivers follow the laws and stop driving drunk, parking illegally on sidewalks, hit pedestrians etc.?
One could hypothesize that if bikes/scooters were given more time and focus, ie, riding to things like school and local errands, then more people would develop skills around riding them.
