I don't see the comparison. BYD is a decent car for an impressive price, but they're ... just cars. The iPhone wasn't "just a phone" that was cheaper than its contemporaries and a little better in very specific areas, it was a complete overhaul of the entire market.
You can look at a BYD and a Nissan and make a decision based on minor trade-offs between different aspects of the car. You couldn't do the same between iPhone and a Sony Ericsson.

BYD car division has multiple departments doing independent R&D and releasing independent lines. They were first with 360° tank turn and now a jumping supercar. They are trying hard to deliver things others like Musk keep promising down the line.
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.
