i guess we should be expecting a samsung self-driving car by this time next year...
i doubt it would triple, but it would probably never go down in price, where the average person could eventually afford one.
Unlike, for example, the price of an iPhone which is very affordable for an average person in the U.S.
Not that Apple stuff is cheap, but most of it is priced at a level that the middle class in the U.S. have no particular problem affording. They can't buy it on whim, but a new iPhone every two years is not out of reach of most people. So a new Apple car every 10 years probably wouldn't be either.
However, I'm pretty sure Apple has no interest in making a car.
