Grid stress in the first world isn't a big problem since electric vehicles can charge when the grid is under less pressure. The demand curve over a day has a reasonably predictable shape and EV charging can often be done when wholesale prices are low. Of course we will need to increase capacity, but that can be done over time.

Fossil power to generate electricity that then powers your car is less carbon intensive than just using an internal combustion engine. The overhead of getting oil out of the ground, refining it and transporting it is big. You then lose lots of energy as heat as you run your engine.
