Yup. Car market moves slowly and requires massive infrastructure. I've never bought a car that was less than 7 years old and I drove it for about a decade. Average vehicle age is 12 years and 1/4 of vehicles on the road are older than 16 years. New cars are only 6% of the market and cars are lasting longer every year, since quality and durability keeps increasing. Really they keep getting better and better.

My best guess is that in 30 years, the majority of cars on the road are still going to be ICE. But in 100 years? Who knows, we might get a fantastic battery breakthrough or perhaps we'll be driving fusion powered cars :P
