-- used to be escooter hell in Seoul - the government passed a law requiring the apps to make sure the user has valid driver license to unlock scooter - since then - considerably less insane --
The only think lacking is better dedicated infrastructute for bicycles and e-scooters alike.
Scootering standards are rock bottom.
There are some fine details, like if you cause an accident while cycling, i think you could get points in your license if you have one, but I never heard of this happening anyway.
Being caught drunk driving an app-based e-scooter is as serious as any motor vehicle violation and will result in your car license being revoked.
