I'm not sure why this is downvoted - this is actually a valid point. If your average charging station handles 24 cars an hour, it does not matter from a power consumption perspective if it does so by having 12 chargers and everyone waiting half an hour or 2 charges with everyone waiting 5 minutes (but the UX will be drastically improved).
The only effect will probably be increased EV adoption, but that's something we generally want and need to prepare for anyway.
