Electric scooters and such do create a new danger that didn't exist before: they let (indeed, encourage) you to take the hazardous part (the battery) inside an apartment to "refuel". An equivalent would be bringing a gas-driven moped into your place which is against the rules in many places, and why would you do it anyway.

As such, it's important to take all possible reasonable steps to mitigate the risk. Those vehicles are still great overall, if only because, between air quality problems and exacerbated extreme weather events, fossil fuels cause deaths, injuries and property damage just through their normal usage. But the danger is there, and needs to be considered.
