First of all, your Middle English grammar is atrocious, the 2nd-person possessive pronoun is “thine”, not “thous’t”. “Thou’st”* is equivalent to the modern “you’ve”, not “your”, and “you’ve actions” doesn’t make sense.
Second, what makes you think there will be fewer injuries with speed-limited scooters? Wouldn’t you prefer they be fast enough to keep up with bike lane traffic so they don’t have a reason to be on the sidewalks at all? An 8mph scooter can still knock you over, and the fall will be the cause of the bulk of your injuries in both an 8 and 15 mph collision.
I’m not saying that they deserve to be unregulated because they aren’t cars, I’m mad that they’re getting the attention of regulators in a way that doesn’t actually make things safer, and districts from safety issues that really deserve attention.
