I'm familiar with Usenet, just wasn't sure if you thought it was for
me.  I suspect you meant someone with a Tesla.

Wasn't me, see above. I commented on the abuse potential with the analogy to 
Direct Deposit. Each discharge costs a bit of lifespan.

Other electric vehicles are capable of supplying 120V AC from their battery.

RVs have long had a similar capability but they separate the starting 
battery from the one that powers appliances, so you don't drain the starting 
battery and become stranded. A plug-in hybrid could still run on gasoline if 
discharged.

I handled field returns of medical equipment Lithiums which kept a log of 
their temperature and charge/discharge history. Typically the trained 
professionals who used the equipment followed charging procedure for about 3 
months before abandoning it and randomly recharging only when they went 
empty. I can't expect anyone else to track and manage remaining battery 
capacity better than they did. A study found that most VCRs flashed 12:00 
because setting the time was too difficult or bothersome.

I sometimes forget to check and let remaining battery capacity fall lower 
than it should be, and I designed the system with lighted wall displays 
showing battery charge level. I almost let supper on the woodstove boil over 
a few minutes ago despite a remote temperature display above the computer. 
Life has too many distractions to expect someone to watch backup battery 
level and not drain their car too far.
