I regard it as a question of scale.

Cars are problematic due to how people use them. That they are used senselessly, agressively, carelessly.

Thats why there are so many rules and fines around cars. Fines that are nowhere near as strong as they should be.

And those same attitude people driving cars in bad ways also ride scooters.

I had a scooter with two on it plow through a tiny gap of elderly people at high speed just a few days ago.

I had a easily 8 meter wide pedestrian crossing in front of my office vlocked in a full line of e-scooters dumped there as parking space blocking it just as thoroughly as if two cars had parked there.

Now if I were to scale up the ratio of people using scooters to the same as cars then it would get very bad because they seem to think of e-scooters as being more free of rules.

Sure, a good solution would be to replace cars fully and use roads for bikes and scooters. Best possibility.

Sadly that's not a thing and until then the people using scooters just as badly as car drivers are out there ruining that for everyone.
