Cool I am probably never going to buy a jumping supercar so that's not very relevant. The iPhone and the smartphone in general wasn't a revolution because it was a super cool R&D project that would cost ridiculous amounts of money to buy; it was a revolution because everyone bought one. If even as much as 10% of the market buys a "jumping supercar" (which would be absolutely INSANE) then there's still plenty of space in the market for traditional cars. There isn't plenty space in the market for "traditional phones" anymore.
