Looking over the animations for the next-gen platform and assembly, and this struck me.
I'm calling it now - eBrakes. I don't see how you can have a traditional master cylinder hydraulic brakes with brake lines running around to the 4 corners of the car with that kind of assembly process.
Bosch showed off a system they said they were working with "a major EV maker" (i.e. Tesla) where it was all Brake by wire (on autoline after hours, if I remember correctly). I fully expected this on the Cybertruck, but it makes sense why you'd need it for the next gen platform! It's all coming together!!!
