I guess in some countries and states? Many countries have deadlines of 2025 (Norway), 2030 (Netherlands), 2035, or 2040 [1], I don't think the hold outs will be able to keep up with ICE production and infrastructure for long after the richer states and countries transition.
And once the writing is seen on the wall, no one will want to be the last person to buy an ICE. Things will change pretty rapidly.
