Your points are very reasonable. However, I think that unless some government funds electric car tech research, the only way is to approach it top down, in a capitalist model. Make an electric car that's expensive, with a very high profit margin. Sell it to the rich. Use the profits to drive the tech advancement. If you approach it by making affordable cars, it will be quite a while before you accumulate enough capital to invest in the technology.
They had one at 53k and another at 55k last week, but those went quick. If you're serious about going electric, keep tabs on that report. You should be able to snag a deal in your price range. The Model S checks off everything on your list except price, and it's just barely out of that range at that.
