I know congestion can be an issue at some sites, but I have never waited in line to charge in seven years of EV ownership.

In addition, for superchargers, you can see real-time stall availability, so if a particular site was crowded, you could just opt for the next. (Easy enough to do since there are so many).

Unless you are going a long way, you charge at home. And rural areas have a lot of independent housing and outdoor power so it’s easier than for city dwellers.
