Is there anywhere on earth where gas is cheaper than electricity? Outside of like the middle east maybe. I suppose you'd have to remove gas taxes for a clearer picture. But that just shows that the government can make electric viable whenever they want by raising gas prices.
This is a bit complicated, since the two are not directly equivalent.
But as an example example, we can compare a 30mpg car with an EV rated at .24kWh/mile (advertised consumption for a Tesla Model 3). 250 miles would be around 60kWh or 8.33 gallons. Power averages (in the US) around $0.20 per kWh right now, gas about $3.38 per gallon. There's a lot of variance by state for both of these, of course.
And so, for 250 miles, gas would be $28.16, whereas electricity would be $12.
So the answer to your question is: Probably. It's only around 2.5x difference in price, which could easily be inverted somewhere that has a significant oil supply but low power generation capability.
