E-scooters didn’t usually replace car trips in Paris, but instead walking and public transport trips.
If that’s the case, and I don’t have statistics one way or another, then we must ask ourselves why people dislike walking and taking transit in Paris and do something about it, rather than banning alternatives.
Laziness ? Ease of bypassing rules ? (slight /s)
Honestly, between the very extensive metro system that pretty much goes everywhere in Paris, complementary bus lines and docked (e-)bikes that are pretty much everywhere in the city, Paris has a very good offer for mobility. Sure, things can always be improved, but on that aspect, I don’t think we can really blame the city.
