Both ICE and EV cars require a support infrastructure. As sales trends change, so the emphasis on support infrastructure changes, and that accelerates the trend.

For example EVs depend on charging, so we're seeing more public charge points, as well as more home chargers, work chargers and so on.

ICE depends on gas stations (which is the tip of the gasoline distribution industry.) It also depends on ICE mechanics. As demand for those services drop off, so they'll become harder to find. (To be clear, that's not happening soon, there are a LOT of ICE cars out there...)

But 50 years from now most of that ICE infrastructure will have disappeared.
