Who has the time to sit around or park their car for an hour for every 20 miles they drive?
If you take NYC for example, EV parking spaces are big bucks and for the few available public infrastructure places, most of the spots are being occupied full time by city parks department vehicles that rarely if ever leave the charger.
As far as taking your question literally, you should talk to people in the midwest more -- I know lots of folks in the Dakotas and Wyoming with crazy schedules and 4hr commutes because that's literally the closest work.
Add in Alaska.
And you're at 3m citizens of 282m vehicles. (< ~1% if every citizen of these 4 states has a vehicle)
Also way to pick out the least significant part of what I said to have a gripe about.
33% allows for 33x the population you're citing; and has an additional 9 years to get there.
