Tesla has laid down some good R&D with their lightweight, fast vehicles, and they've attracted a lot of attention by proving how quick an electric vehicle can be. I'd like to see some cheap featherweight vehicles in the future...

As far as making electric cars cheaper, Lithium will be the new gold if we go the way of Tesla. It must be mined from pegmatites and granites. There's also the downside of Lithium being highly reactive and raping the environment if dumped.

I want to see cheaper NiMH or Fe based energy storage for electric vehicles. But realistically, batteries in general are either heavy, toxic, or prohibitively exotic for large scale production. Lead, Cadmium, Lithium... If battery powered electrics were to be widely produced, we'd need to use the most eco-friendly and common battery materials like iron and nickel rather than the most efficient and light (and exotic).
