Wheel mounted electric motors are not that new. The problem of wheel mounted electric motors is the problem of the unsprung mass[0]. The thing is, that you don't want such things, at least for higher speeds.
Also Schaeffler was working its version of the E-drive wheel for years. Just another release of another (new) version about 10 years ago[1].
Also working on inductive charging is nothing new. Just from the release, it is unknown how god that worked. I new research that is more than 10 years old on inductive charging for cars like in parking spots or at a traffic light. The problem of inductive charging still today is, if you are not perfectly aligned you will waste a lot of energy. That is why the charging in the smart phone are all have magnets. That's to guarantee a perfect position. Should car snap in place, when you are in your parking spot?
So while this release is interesting, it should not be to exaggerated.
