Yeah, this would be great for commuting as a single driver. Certainly wouldn't be able to do much else, so if it was around $10,000 then it would be reasonable as a second vehicle. Hybrid version would be a good idea, but I suppose getting it as light as possible is also in the plans, maybe using Lithium they could do it, but then the price is inflated by a magnitude.
