After you have waited for the 3 or 4 cars waiting in line for a charger ahead of you.

That's never even been close to the case for me, and only rarely has that been a problem reported in the reputable press, as far as I've seen. I've never been deeper than second in line, and that was years ago when the CCS network I then relied upon was kinda pitiful. Chargers now are abundant, the NACS (Tesla) standard is dominating, but my cars are able to use it or CCS which still has a fairly robust network. You can generally see online if the station you are looking at is full or not. If it is full, then you look to another station. The technology is pretty simple, and electricity is already available most places where you'd think of putting a station. At the moment it still takes more planning than gasoline does, but that is becoming fairly low effort and much more flexible than it used to be.

Stuff happens with gasoline and diesel availability too. I've seen at least two instances in the last few years where people were queuing up waiting for gas, taking up a lane of traffic for a block or two away from a station that had gasoline at the moment. Sometimes people even queued up outside a station that was due to get a delivery but didn't actually have gas at that time. Or they drove 40 miles away to an area that had regular availability. That's inconvenient if you were trying to evacuate, as happened in my home town when Helene hit a couple of years ago.
