The path we as a society ultimately take isn't up to any one entity making decisions (not even Elon Musk :-) ). Certainly lifestyle transitions will require decades, after all, it took decades to cities to become car-centric. But can happen even within a generation. Many millennials eschew car ownership and are moving back to cities, whereas for baby boomers the car was a rite of passage as well as its concomitant house in the 'burbs. Transitioning entirely to electric vehicles will also take decades (admittedly it would be less time because car-years are much quicker than people-years). What will happen is some mixture of both of these along with random jags of reactionary fascination with the happy-motoring era and who knows what else. Ultimately, we only have a finite quantity of fossil fuels and there is no "free-refill" for the planet. At some point, lifestyles will have to change drastically to accommodate this limitation as population continues to grow.
