If you took the gasoline that powers one car and put it in a power plant that powered EVs, you could power maybe 4 or 5 EVs with that gasoline. So even that is a net positive.
Why? Because converting gasoline to electricity in a large-scale plant is far more efficient than converting gasoline to motion in little engines scattered about in the environment. Once the power is available as electricity, the downstream losses are really quite small (10%? 5%?) compared to the downstream losses for gasoline - 85% just in the car itself, and that's not even including delivering the gasoline to the gas station or the energy required to pump it into the car etc.
