@dmoren I had the same thought, but I **think** it's based on location services not any sort of comms with the car.
But apparently it needs enhanced support on the car side regardless, so you and I are SOL anyway :(
They’ve been using accelerometer to lock out iPhone functions for years now.
I’m talking of the iPhone in general assuming it has -something- to do with CarPlay for most users. (Could people be connecting their iPad instead? Probably, but could that take calls, an increasingly dubious need for some these days?)
But I doubt just because some interface elements have moved to a dash screen that iPhone would surrender its ‘car is moving don’t do that’ protections.
Movies/TV on the back headrests for passengers? Already in the wild w or wo Apple.
