I wasn't asked but I have a very passionate opinion on them. So if you'll allow:
spoiler
The way they're utilized in Germany fucking sucks. It was advertised as a "last leg of the road" kinda vehicle. And where are they overproporionatly available? In cities.
Where do you have good infrastructure and public transport? In. Fucking. Cities.
Meanwhile people who really really need a way to get around in rural areas remain to be dependent largely on cars. There usually are busses driving to villages, but only few a day.
They use resources such as batteries that I'd rather have used for other e-vehicles. In the beginnig they caused new low pay/exploitative jobs: juicers, i.e. the people who collected the scooters and recharchged them at their home.
And lastly the users. Thet zip through pedestrian zones at ridiculous speeds, drive on busy streets, park them in the middle of the walkway or throw them into nature.
I hate them and they have shown very little upsides imo.
The only thing I can think of was my buddy getting home after we hung out faster at night.
