The massive savings aren't always massive. If you use fast chargers frequently, it's going to cost you. In contrast if you use a slow charger regularly at home, then you'll save money. But that's not really an option for road trips.

I'm explicitly not buying an EV yet because there are no massive savings on gas where I am for the amount I drive. My current car cost like $12k used, and at the time a comparable electric used car would have been like $23k (and would have had like a 80-100 mile range, which I would have been fine with). But we spend like an average of $400/yr on gas and $75/yr on oil changes and extra maintenance above what an EV needs, so we'd be looking at 10++ years of difference to break. Even assuming free electricity and no higher licensing fees (which combined would be more like $200/yr). So actually more like 20++ years to break even there (which is basically not happening).

If I lived in an area where gas cost $20/gallon instead of $4/gallon, then it would change the math a little - it would be a net of more like $1300/yr, and I might actually spend less on an EV in the long run (7 years to break even, assuming 0 opportunity cost on the $9k).

If I spent $20/gallon on gas and also drove 12k miles / yr instead of 3k miles / yr, then it becomes a much better proposition.
