Yes, there needs to be support for ICE vehicles in certain areas for quite some time to come. Until EV technology can support those that rely on gasoline or diesel powered cars in remote places.

Once the fossil fuel infrastructure starts to lose mainstream use, folks that require larger range, better cold weather reliability, etc. will pay through the nose to be able to move freely using their existing cars.

It will be a slow transition until it's not, and then you have a bunch of useless piles of steel, glass, and rubber lying around.

I wonder how they will handle emergency and military vehicles in the future. For any of them to use it it has to just work, and work quickly.
