I regularly do a 200 mile mountain pass with a 75MPH limit, and have been explaining all this to my wife regarding our new Tesla.
But I'd have never admitted how much more efficient our old ICE car would have been at 50MPH than the usual 85MPH I preferred (it's 3 lanes wide and empty, so it's not unsafe to go slower, I just didn't want to).
Battery swap is probably not the way. My prediction is charging times will get much faster with better battery tech in the next 5 years. We might be able to get a full charge in under 10 minutes - which starts to match the convenience of a gas fillup.
I don't see manufacturers agreeing on a standardized battery pack size and shape. I also don't see battery swap stations getting built to the density needed, even if only as a supplement to charging stations. Battery swap stations would be significantly more expensive to build and maintain than charging stations.
Regardless, we don't have battery swap, and I don't think any (serious) manufacturers have plans to go that route, so it's a moot point.
