> e-bikes in particular run much faster than regular bikes and are used much more by incompetent bikers, given they are basically a non-taxed non-regulated non-plated moped (mopeds are quite dangerous for pedestrians)

This is factually false, or at least, in several countries, where their design is regulated:

1. the engines are limited to 250W, which is not weak, but not strong, either;

2. some even have an electronic cap to 25 km/h, and engine turns off after such speed (I believe this is for mid-engine models);

3. can't propel on-demand.

E-bikes are also heavy, not aerodynamic, and don't put the driver in a position to push stronly. The speed demons who overtake me in the streets, are typically non electric racing bikes.

I had both types, and they definitely assist the ride, but they don't push the driver to go faster.

Wheat fits the description you've given are actually electric (kick)scooters:

- they propel only on-demand

- they're often driven by reckless teenagers, which sometimes bring a passenger

- since they're smaller than bikes, there is a considerably lower (both physical and psychological) barrier to traveling on the pavements
