There is a lot that Google is telling us that they’re not saying in this video.
 1) That manufacturing process they’re using looks remarkably similar to Gordon Murray’s iStream. Just see that tubular frame chassis and (what appears to be) bonded plastic panelling. The framework design seems very much like the Yamaha Motiv.e. Of course, if Google was thinking about getting into making its own cars, doing so via a fully formed and disruptive method of car manufacturing would be a good way to do it.
