I agree with what you are saying here, but how would you feel about the fleet having a baseline behavior, that is specific to every car in the fleet, but then having an AI component that makes the car drive more like the driver does? Baseline would be pretty much how Auto Steer functions today, for whichever level of autonomy the customer has paid for, but then AI could make adjustments for things like how quickly I pull off the line, or how closely I follow the car in fort of me, or when I change lanes I over take or I allow others to pass? These little nuances could enhance the AP experience and make it unique for each driver based on how they drive.
But...you’re paying for their driving software to drive you, not...to learn to drive LIKE you. When you take a cab, do you insist the cab driver adopt your style?
