In watching the test drive videos I didnt see any AP sensor hardware on any of the Model 3 cars. Did anyone see any? Perhaps it will be the rumored AP v2 sensor gear by the time the Model 3 comes out and they didnt want to show that stuff yet?
The prototypes I'm sure were bare minimum to be drivable. The sensors and software are still being worked on. Likely the testing is all happening on Model S / X development cars at the moment and foreseeable future.
