The Netherlands had a similar thing for a while. From age 16, teens can get a moped license. Within the moped class there are tiny 4 wheeled vehicles. Mostly a continued development of tiny cars used by people with disabilities.

Then somebody figured out that some real cars can have their software 'downgraded' to limit the car to 45 km/h, and it can be classified as a moped.

I forgot what was done to get rid if this loophole.
