Depends where. EVs are already 23% of light vehicle sales in California. The US won’t transition equally.
And the median car is 13 years old and getting older. If the market share is only 23% today, then in 2040 the fleet will still be overwhelmingly ICE-powered, unless the government starts pulling levers that accelerate the transition, like quadrupling the fuel taxes.
EV adoption is incredibly uneven. It makes predictions really difficult.
