Taipei is full of mopeds and now in much the same way Austin, TX is becoming full of scooters.
People treat the scooters and their usage as a toy. You are going 15 miles an hour down the road, and you've got people and other cars. It is not simple. Yet, because getting a scooter via an app is so easy, people don't feel the appropriate degree of caution. Most people don't even wear a helmet.
Most of these companies do not seem to provide helmets for riders. Perhaps there is room for a company that could become a helmet vendor to all of the scooter sharing startups.
