So, based on your statement, you're saying that if you don't like cars that means you must love all alternatives and never ever point out any issues with them even if they are utterly legitimate?
You are comparing something that has laws and rules, a dedicated place to 'drive' and have billions of miles driven.
Right now in most places these scooters follow whatever laws they want (if faster in middle of street, it is there, if faster on sidewalk, it is there). People aren't accountable (no driver license, hard to track) and idiots.
I just wish people who are anti-scooter would interrogate their own opposition and understand its true genesis. It's not road safety. Road injuries are almost exclusively due, in various ways, to cars. So what is it, really, that's bothering them?
