The unfortunate reality is that nothing has solved the last mile problem for public transportation as well as these scooters have.
Say you want to go to the store two miles away and don’t have a car. What are your options? Walk for an hour round trip, take a slow bus if you’re lucky enough to have both where you are and where you’re going on a bus route, or overpay for an uber/lyft/taxi, which due to their cost structure are generally less cost effective for shorter trips.
I agree the safety issues are of concern, but there’s really no better solution currently to that problem, which has been the hardest problem to solve since the advent of public transportation.
