faraday definetly had a lot of hype around their booth, i have never seen such a long line just to see the other side of a vehicle. I hope they succeed and drive more innovation. Tesla needs some constructive competition.
I was digging through photos from past CES shows (+5 years) to see what innovations stuck, and which ones floated away. LED technology has come a long way, and so have batteries. Things will continue to become more mobile and portable. AS far as what sticks, i think a lot of it has to to with whatever perks societies interests.
