There are a lot more cars sold (82.8 million in 2014), then planes sold (2331 in 2014), so the cost of the autopilot is distributed over a much larger userbase.

There are a lot more cars sold (82.8 million in 2014), then planes sold (2331 in 2014), so the cost of the autopilot is distributed over a much larger userbase. Not to mention that a plane crash is a much, much bigger disaster then a car crash, and that the salary of the pilot is only a small component of the cost of a UPS/Fedex flight, compared to the cost of the driver for Uber. As for Uber benefitting more then Lyft, it comes down to who gets them on the road in scale first. If Uber is the one who creates the software behind the cars, they dont have to share. Of course the risk is that the car manufacturers will create their own network (Tesla has already indicated this is what they will do).
