^Good points; I thought of them but did not comment...
Re: transmission: I like their layout, it looks quite compact and efficient to me. The one driveshaft passing through the motor looks like a clever solution to achieve the most direct power transmission path possible with a transmission. I believe that EVs need transmissions for best efficiency too.
Re: key not turning: I read that and thought they are going to need a special heavy-duty key and lock because otherwise a lot of keys are going to get twisted off!
