In China it is already becoming common for people to plug in their personal/family conveyance for the night. Not the conventional four-door sedan, of course, but rechargeable electric scooters are quite commonplace. I don’t know if any of the electric scooter companies would be particularly interested in investing in fusion, though. I imagine they’ll treat fusion power the same way the ISPs treated IPv6: they’ll use it when they need it. The obvious difference being that IPv6 was in existence, if not widely tested, well before it was needed, whereas we don’t yet have such a guarantee with fusion power. The other obvious difference being that it’s not the scooter companies’ business to supply the electricity for their scooters, although their sales would no doubt be affected in places where power outages were common.
