Someone does need to pay to maintain the roads, however, and if ICEs become a smaller and smaller part of cars on the roads, the gas tax will cover less and less of the cost (and they already don't fully cover the costs of road maintenance).
In my state (MN) I'm actually paying more in annual EV fees/taxes then if I drove an ICE vehicle of comparable value
There's a similar shifting dynamic in solar power, where much of the cost of utilities is actually for distribution and maintenance, and as long as you're connected to the grid you're contributing to that cost, but to encourage people to use less power more of the cost is priced into the $/kWh price, which all breaks down when you're generating most of your own power but still using the grid.
It's an interesting economic problem, and I don't think there are any super obviously "fair" solutions right away.
I can think of a lot of examples, eg. Internet media destroyed the monopoly of old media, which made it uneconomical to do serious investigative journalism, which further reduced the quality of old-line media, which accelerated the switch to Internet media. Private/magnet/charter schools brain-drain the best students out of public schools, which decreases the quality of instruction, which means that you need to start looking at private/magnet/charter schools if you want your kid to have a decent education. Automobiles incentivized the creation of road networks and parking lots, which took up so much space that you can no longer walk anywhere, which requires that you get a car.
Usually it results in the total destruction of the old industry, and then the new industry develops some taxation/regulation scheme to cover common goods within the new technology regime.
