Electrification of transportation and other sectors is the last real opportunity for growth for electric utilities, which is why they're all in favor of it, while the oil & gas companies are resisting it, of course.
EV sales will probably grow exponentially (especially in countries that have a deadline for cars with combustion engines) but in terms of cars on the road the transition is going to be slower than it could be, no different than how investment in new coal generation is essentially dead and it's dying for natural gas now, but the retirement of those plants and their decline in market share isn't going to occur overnight, of course.... That said, if more US states incentivize EVs like they've incentivized renewables, then that could expedite the transition.
Automation is the variable in all of this, of course. Autonomous technology is more compatible with electric vehicles to complement mass transit, and same goes for local commercial / municipal vehicles (for long-distance freight/trucking that's a different story, of course, regardless of what capacity the batteries can get to increase range).
