There are situations where I've considered using an e-scooter because existing infrastructure is insufficient or just plain unreliable. If a bus or two or three are cancelled and I'm really frustrated, even a car seems like a great solution, regardless of environmental cost. E-scooters seem like a decent alternative (depending on how reliable and environmentally friendly they actually are). I'd even consider buying my own, but it seems Germany is lagging behind in allowing e-scooters in public (the only two models that are purchasable that are also street legal cost 2000+ Euros).
