Given some definition of "suddenly". I don't expect everyone to run out and buy brand new cars off the showroom floor en-masse the instant the economics favor the newly available flavor of shiny. Cars are big ticket items often involving financing, they're sticky. This is why it's pretty damn urgent that we get the competitive EVs on the market ASAP. Every new ICE vehicle we add will be on the roads for quite some time, especially with how mature/reliable they are today. My 94 Japanese econobox has nearly 300,000 miles and still runs great. The other issue is as increasing numbers of ICE vehicles get replaced by EVs, the gasoline demand drops, and the prices may correspondingly drop. In the words of a friend of mine: "All the oil in the world will be burned."
