Battery technology is not yet (though very very close) advanced for total electric only. It (any hybrid) is just a bridge to total electric.......

“Battery technology is not yet (though very very close)”

Let’s see:

This battery holds about a kilowatt watt hour which is about 1 horsepower hour when the efficiency of battery heat losses, controller, and motor considered. Drain must be limited to 33% for maximum battery life. Battery weights about 60 pounds and costs $2000.

A very efficient car can run do 60mph on 12 horsepower.
You would need 36 of these batteries....2160 pounds ....$72,000 to drive 60 miles at 60mph.

I think we’re still an order of magnitude away from the right batteries, and probably 2 orders of magnitude if you the existing performance and comfort and price of todays average car.

Not very close, much less very, very close.
