I don't want an electric car.

A hurricane comes. There's an evacuation. The interstate is a parking lot. And eventually all the electric cars run out of juice with no possible way to get them away from the hurricane.

Or there's a blizzard. The roads are packed with electric cars. The road becomes impassible. People freeze before long. Batteries don't last long in the cold and heaters really run down batteries. A gasoline car can be shut off and run only occasionally to keep the car warm enough for survival for a very long time.

I think you'll be waiting pretty much forever before you get an electric car worth anything that will run on solar panels on its roof. You can cover an average size car with solar panels and get perhaps enough energy to go 3 MPH, if the car has super low rolling resistance. If solar panels were 100% efficient (though impossible), the car might reach 25 or 30 MPH, not even fast enough for in town driving.

The only electric car powerful enough to be worthy is the Tesla Plaid. I know a millionaire who owns two, because they take so long to charge up, he keeps one on the charger while he drives the other. Over $100,000 each plus a year wait was easy for him, since he already had gas powered fast cars.

There's a reason gas power has been around so many years and wasn't touched by the previous electric cars of 100 years ago. It's portable, concentrated energy.
