Well, they are already doing interiors better than Tesla, so there's that.
As I pointed out in the BMW EV thread, BMW is currently grappling with the issue of everybody who wants a BMW likely already having one, so they have a fight on their hands trying to convert other brand buyers or encouraging existing buyers to upgrade. This is the position that most major brands are in. That's not an issue Tesla has yet, they are still in growth and expansion mode but at some point market saturation for those who desire one will put them in the same place that all the other marques are in right now. I have no idea when that will happen, but it is inevitable.
