The question is whether we have enough time for this to happen gradually before we cross the climate tipping point and are stuck with the new one for hundreds of years or more - I hope so, but suspect not.
That's a different question. Electric cars are going to be the cars of the future because they are better as cars, not because of environmental reasons. Even looking at environmental reasons, dirty air in cities is probably a larger reason in many cases. Subsidies and mandates for environmental reasons are just speeding up the transition to EVs, not doing something new or different.
Climate is a slowly reacting beast. Not decades, like major economic changes or hundreds of years, but more likely many thousands of years. The E-folding time of Carbon outside of geologic storage is around 100k years. Better like the new climate.
