Have you calculated how much money a typical driver would save in fuel due to losing 34 lbs of weight?

I have no idea if this ends up being a significant number, but I think the average driver spends somewhere around $10k in fuel over the expected lifetime of this battery; if cutting down the weight by 1-2% reduces fuel consumption by a comparable amount then Ohm would pay for itself.

It depends on a lot of things of course, but yes, over the lifetime of the battery, it will pay for at least a large percentage of itself. We estimate about $10 a year gas savings.

Wouldn't it be cheaper for them just to eat less?
