Pretty sure that cost is going to come down significantly with EVs. Batteries are only going to get cheaper, you have less maintainance cost. Solar cars can fuel your car for the average driving distance in most places. I think smaller city EVs will become much more popular, anything between an e-bike and an electric Mini. So those will be much less expensive to buy and operate.

The only things keeping EVs expensive is just the early adopter "tax" and the high cost of batteries.
