What the grid can't handle is if everybody all at once needed a full 300 mile charge in 8 hours, while they are showering, running ac, and factories are producing. This is partly resolved by sun heating, cold sleep patterns, factory shifts, smart charging, and that 95% of consumers do not make 300 mile daily commutes.
Substation and individual point of charge capacity may not be there for areas without ac, or high density apartments - but that's where distributed charging stations come into play (aka charging stations) (very low volume of gasoline is distributed to home parking, currently). In the worst cases this is readily reduced with storage (liquid or power wall) at distribution centers.
