Yeah, they had protests and wakes here over that.General Motors called all of their electrics back off of lease and DESTROYED EVERY ONE OF THEM.
I suspect the reason originates in lawyers' offices. You could sell people the cars and have them sign liability releases, but you could still get your butt sued if a battery leaked or someone got electrocuted monkeying around with it, say, to make it work after official maintenance was cut off.
Just my guess.
