Would still need friction brakes for the front wheels and for parking, but could save a lot of weight in the back.
I also had this in mind, but I thought this would raise the amperes in the motors dramatically... requiring additional cooling for the motors...
And I won't think of having more complex motors and additional torque on the gears, which we know of being a little bit fragile 😕
And having 'real' brakes might be a security requirement... think of going into 'reduced performance' at 120mph 🏥
