 Absent some revolutionary new technology, I suspect you may be right. Mind
you, we have people who are quite happy to only be able to drive for only
200 miles in an EV and wait several hours between re-charges.

Tesla's super-chargers are quicker than that, and 200 miles is a rather short range for modern EV.
And electricity is quite a bit cheaper per mile than gasoline.

And suffer a
*massive* deprecation on their 2nd biggest asset. *And* pay a fortune to
have their old battery recycled. Fuggin' idiots.

The "massive depreciation" is a temporary blip in a developing market.
The fuggin' idiot here is Cursitor Doom, who would still be getting around by horse and buggy, if he could afford it.
