> Paris

With 2000 escooter accidents and 20+ deaths idk if we can call it a great example

Now do car deaths. If 20 is the threshold for failure then get all those cars off the roads immediately.

Well, yes go ahead I won't argue against that

edit:

I checked the numbers, ~6000 accidents, ~40 deaths

Knowing that it includes escooters as they're motorised vehicles, and given the number of cars vs escooters I'd say you're muuuuch more likely to get wrecked on a escooter than anything else you could use on the road. Bicycles have the same deaths stats as escooters but in Paris we have

450k+ cars 500k+ bikes 15k escooters

Wow, I'm surprised the annual car deaths in Paris are so low. Your vehicles are much better behaved than they are in the US, where car deaths are rampant. NYC for instance experiences >200 deaths caused by cars/trucks every year, and that's a relatively low rate relative to our population size compared to basically any other large American city (all of which are much more car-dependent).

Wow so e-scooters in Paris are net negative for society.

Over what period of time? In a year, those numbers don't strike me as terrible and would need to be compared against the alternatives to draw a directionally valid conclusion.
