After Elon Musk so helpfully pointed out that once cars are self-driving there is absolutely no reason for companies to sell them to us, I have to say I hope it never happens. Why would a company sell me a car for $30,000 when it can add it to a self-driving taxi fleet and generate $300,000 in revenue over the lifetime of the car?
