Your comment makes A LOT of assumptions - in both ways e.g.:
- you are ignoring the benefits that EVs could bring, as well as synergies with future technology improvements. Radically better battery technology coupled with cheap, affordable solar might be a game changer of unprecedented scale.
- On the other hand, there's no proof that "drastically reducing the low-occupancy car miles driven" or "reversing the car growth trend" is either feasible or beneficial (how do you achieve the goal? Any measure is likely to have side-effects. I haven't seen any realistic proposal that doesn't have potentially horrible side-effects).
Lastly, let me just tell you that I love it when people living in developed countries know what developing countries should do (which is typically "stay poor", but delivered in a more politically-correct way)
