Would an All-Electric yaris be cheaper in the long run?

[why?]

Like most water heaters, ev's could easily be programmed to charge at a certain time.

The biggest argument against them has not been presented yet: Range. Even the Chevy Volt, supposedly the most advanced hybrid, can't go squat on battery only. Battery technology is not even close to where it needs to be for ev's to be useful. A range of at least 200 miles on a charge at maximum of 8 hours is necessary.

And then price would be an option. Most sources say no car manufacturer selling a hybrid is making money, and even the most optomistic say that Toyota is just finally starting to see a profit from Prius sales.

How crazy was the GM EV1 lease? Like $600 or more a month? That's insane.

Electric cars existed in the 1800's, then were dropped for gasoline. Technology isn't quite what it needs to be for them to be a reality yet.

And then, say the range is decent, the price is alright, you have to calculate electricity costs and all that other good stuff.

And, no the grid is not up to it. Like up north, when we in Florida just had our coldest days, the electric company was on the radio begging people to conserve electricity, and they still almost had to resort to rolling blackouts.
