I don't see that happening. Will they make it harder to have IC? Yep, and that's within 5-10 years. What I suspect may happen in regards to old cars is a new generation ditching the IC and going with an electric conversion. It's technology and youth embrace it. And that will turn off the older generation and when there is a shift in the guards or so to speak.
But I don't have a Crystal ball and could be completely wrong lol....
