If the shift to EV is going to happen it will need a greatly upgraded electric grid.
In the summer on hot days you can see in major cities warnings about brownouts and high use/demand just simply based on people turning on the AC.
If the infrastructure is not able to properly deal with the demand then there will be a point that buying and EV comes with the risk of it not being able to be charged or fully charged. As oil dependency shift to electrical dependency.
Add to that a shift will also be needed in how the electricity is generated..
