If the “Lindy effect” holds true for the 911, it might be quite a long time before the 911 and its variants go out of style.
The same cannot be said for the cyber truck, and all of the other short lived prototype cars that have very harsh angular lines.
The 911 has the highest average resale value, relative to the original price, of any car on Earth. It depreciates less than any other vehicle. I don't think you're going to be correct.
I don’t think that’s how the end of ICE vehicles will happen.
It’ll be death by a thousand cuts. New ICE vehicles will be increasingly rare in showrooms. There will be bans in city centres. Gas stations will start to disappear. Those that remain will be required to sell blends with increasing amounts of non-fossil derived gasoline, which will be considerably more expensive than current prices, and far more expensive to run.
Eventually, driving ICE vehicles will be like horse riding today - a niche, expensive, smelly hobby that is conducted well outside city limits.
