Do anyone know why electric mopeds are still rare in US, even in big congested cities? In China there're already hundreds of millions of them running on the road.
None of that stuff is an absolute dealbreaker, but if I have a bicycle to schlep around the borough and a car to get into the city, getting something in the middle is a tough value prop.
US roads are full of large vehicles and plenty of distracted drivers. In sf, you appear to be able to kill bikers and walk away with a ticket unless you're grossly negligent.
The biggest thing a car has over this is 2k+ pounds of crumple zone surrounding you to take one for the team.
