I've been doing EV road trips for four years now and I've never had to queue for a charger.

A recent road trip I went on about a month ago, I pulled up to the place I was planning to charge (an EA station attached to a Walmart, was going to go to the deli for a snack while it charged). It was completely full and seemed like there were a few people waiting. I just drove to another charging location about 2mi away (a 7/11 station I think?) and charged there and had a snack. No big deal.

That's about the closest I've had to queue in the past few years. Other than that, there have usually been multiple open chargers available. And once again that's only when I've road tripped. I've had to waste far more of my life pumping gas in my non-EV than I've spent waiting on charging despite my ICE getting far fewer miles.
