Who says you need Ford to do it? Aging Wheels tried a prototype of a small electric pickup a year ago from a team making one without the support of a huge car company. I have no dog in this fight, other than wanting more of transport to go electric but if Americans refuse to buy vans which probably make more sense for transporting goods this might be a good option.

You don't need Ford per se, but you do need an experienced manufacturer to take a concept car to mass production, and you need mass production to make something affordable.
