Almost no one, in that demographic, yeah. And I think that demographic
(just getting by) is going to include the overwhelming majority of ride-share
drivers, because it doesn't pay well enough to raise someone out of that
demographic, and it's not really a highly regarded "dream" profession that
a person with other means of support would do because they think it's
important (like teaching school or medical work) or just plain love doing
it and don't want to do anything else (like art or music), at least not for
most people.
The price gap between traditionally powered vehicles and electric ones
is narrowing, but it's narrowing fairly gradually, and I don't know that it'll
necessarily be down to zero by 2030 (for the new vehicle market), and
if you want drivers of older used vehicles to all be using electric by 2030,
the deadline for that price gap to narrow to zero is more like 2010, and
that ship has sailed.
With that said, superficially, a $4k subsidy is substantial enough that it
might *sound* like a real windfall to some people, and fear of missing
out on that deal (especially if it's advertised with a prominent and
imminent expiration date) might potentially motivate some people to
try to stretch for it. Dunno.
(Presumably there will be car dealers who will go out of their way to
provide financing that allows people to overextend and buy a more
expensive car than they can really afford, with a loan term so long
they won't be able to afford the maintenance on the car by the time
it's paid off. It's a sleazy practice, but it would neither be new, nor
unique to EVs.)
