Since all cars now being produced have the autopilot hardware, I'd think they'd also have the electromechanical braking system (since it's needed for autopilot).
that would be very nice... I ordered with pro seats.. wonder what they will install now when the new seats are in the P85D
I don't think P85 seats will change...not any time soon. I think the D will have that premium interior option as a distinguishing feature for the D. Although Tesla mentioned that a retrofit would be available (they do look comfortable!), it probably won't be cheap.
