The big problem with EV cars is the range and infrastructure to charge vehicles in the wild.
As we near a self driving future, a couple things could happen.
1. Cars could drive themselves to charge and park themselves
2. We can build charging stations everywhere
3. Maybe wireless charging spots
4. Charging drones that your car summons.
I was thinking I just solved the world's problems with idea 4 but option 1 is more likely.
