> Here (not France) you can drive an EU moped (45km/h) on a car license, which could (and should!) be a great alternative to a smaller car. The problem is that it's difficult to get to and through the city without touching the highways, which are strictly off limits for the mopeds for obvious reasons.

In France you can ride a scooter or motorcycle with a displacement < 125 cc with a car license. Certainly not ideal for long trips, but it’s enough for small stretches of motorways in the daily commute. Indeed it’s a good alternative to large cars but it can be dangerous depending on the state of the roads.
