I've never had a car that did that. It was always the rear for rear wheel drive cars, or the front for front drive cars. The one extreme example of that was the a Corvair I owned for less than a year. It died like most Corvairs, going in reverse while in a forward gear. The autocross guys loved being able to get the rear of the car to go around the turn almost in front of the front wheels.

Tonite's news report on tellie said the person
plugged the wrong charger into the e-bike/e-scooter.
(and parked it near the doorway, so the fire blocked them from
safe normal exit!)

I guess people have more than one "micro mobility device"
and get confused about chargers. 
But I'm a bit surprised that these products
use the exact same DC connector (but only a bit surprised).

the other theory is that some folks are buying refurbished
battery packs, and we don't know the quality of that
refurbishment.

Most people here now travel by jetpack.
I have even seen a couple flying hand in hand.
They keep it on even when shopping!
