You realize that nobody will care as much about most of the things they currently care about when buying a car. Performance? Mileage? Handling? Horsepower? Fucking irrelevant if I'm chilling in the back seat and my car is just getting me to where I need to go.
So what still matters? Price. Comfort. Amenities. The upsell becomes the main sell. At a certain point, Tesla isn't even selling "cars" so much as it's selling mobile offices to one segment, and mobile living rooms to another segment. I could also see Tesla finding a way to place the burden of price elsewhere and offer effectively "free" cars to consumers. For instance, leasing or selling fleets to employers. Or to cities. Or to Uber. Or to Amazon.
Uber, on the other hand, sees a world in which nobody owns a car, nobody drives a car, and everyone hails an automated car whenever and wherever. Like that scene in Minority Report.
Both of their strategies are banking on the idea that cars, as we currently understand and experience them, will eventually become pure commodities. The difference is that Tesla is seeking margin and Uber is seeking volume. The cliche that Tesla is Apple and Uber is Amazon is sort of true in that respect.
