Making lighter vehicles is a big strategy to make electric affordable quick indeed. Maybe some companies will manage to find good solution and implement them quicker than car makers? Renault managed this with the Twizy.

I investigated myself plugin hybrid vs full electric, and full electric won for the simple fact that a plugin needs to be charged every day I will drive somewhere. For the electric, I can recharge it once a week or twice a month and it will cover my needs. I don't have an in-house charger so this is a massive difference.
