I completely agree with your take on Range Anxiety. I see it as an imagined problem, not a real problem, and it is mostly imagined by people viewing electric cars from a distance. When divers of gasoline cars try to imagine life with an electric car, they tend to conflate gasoline and electricity. A more useful analog to an electric car is a cell phone. Unlike a gasoline car, you don't wait until your cell phone's battery is down to 10% before charging it. You simply plug it in every night, whether it needs charging or not.
Tesla's Superchargers have probably done more to allay the fears of non-EV drivers than they have actually impacted Tesla owners. Obviously, Superchargers are nice to have when you need them, but for most owners, Superchargers provide only a small fraction of their monthly charging.
In my experience, the only time RA can become a factor in a Tesla is when the outside temperature drops below 0F. While Tesla has improved its range prediction capabilities, there is still a little bit of human intervention required. What people in gasoline cars are unaware of is that their cars also use more fuel in the cold.
A gas gauge is a very crude measurement device. How do you really know how many gallons are left? An EV gives you real data to work with.
