> If you eliminated all gasoline cars tomorrow...

A carbon tax would not eliminate all petrol cars tomorrow, would it? It would increase the price of fuel, which would encourage some to make their next vehicle an EV in place of ICE. It would inevitably encourage cities and petrol stations to add EV infrastructure too.

Not entirely sure how the US taxes vehicles, but personally I would put some combination of fuel (carbon) tax, increasing monthly well in excess of inflation and a vehicle tax that cost some combination of vehicle weight and emissions. The combination effect of which would be to discourage ICE, pickups and 4x4s whilst encouraging smaller EVs.

Clearly increasing gas taxes doesn't eliminate petrol vehicles, because I've been to Europe (where gas prices are radically higher than the US — +50-100%) and they still have cars there. Yes, the incentives structure means those cars are smaller, lighter, and more efficient — and in many countries, increasingly electric — and that's a good outcome / example of how taxes apply positive pressure.
