I like how ''going electric'' means you're not burning fossil fuel.
The you plug the damn thing into a coal fired electric grid adding an additional conversion to the energy. IE: lose more energy to heat than normal.
Bonus points for taxing the grid when the 'coal grid' is a lot more stable.
On the batteries, I don't know about the Tesla, but the Volt has it set to where the battery is dead when it gets down to an 85% charge. That's done for warranty reason because the li-ion batteries are so expensive and they need to outlast the free replacement timeframe. Not to mention all the costs and environmental damage to mine lithium and dispose of all the batteries.
Barbie Jeeps just aren't the answer right now. Technology needs to make a couple of MAJOR leaps before those things are even remotely viable to replace a gas burner.
