You've pointed out that the omnipresence and logistics of cars are fundamental to entire cultures and cities, and yet when something new is introduced that clashes with that, you're claiming that the people calling for the revocation of the new thing are gaslighted by "proponents" of the established thing - the thing that is cemented into the design of the world already. Given the options to roll back the scooters or redesign a part of civilization, though the latter may be an ideal, surely the parents of the dead calling for the former are not being unreasonable, and even more surely are not "gaslighted"?
