The sentiment of this argument parallels arguments made against cars when they started becoming common (suddenly over the place, dangerous, a nuisance). These complaints about scooters are a bit humerous because cars are still a nuisance, dangerous, littered all over. The difference is cars are a bigger danger, bigger nuisance, and if you think scooters are littered all over the place, have a look around at how much space all these cars are taking up! :-)

We can get through this transition period and put in place reasonable rules that yes will eventually become commonly complied with. License scooter drivers and or the scooters themselves. Reserve one street parking space per block for scooters and you probably could cram 20 of them in there. Lots of things can be done.
