So thing to point out is that the average driving time at least for me living on the east coast of the US is about two hours, which requires a stop normally to use the bathroom at that point. (Note I am not old, 26, so it isn't a bladder thing... I drink a lot to stay awake during my driving and that translates to stops.)
2 hours of driving is around 120 miles which is about the average distance between chargers. Some were longer some were shorter. That recharge time is only about 15-20 minutes tops. In most cases I was stopping plugging in, walking over to where I could use the bathroom and get a new drink and then walking back. By that point I was pretty much ready to go again. Some stops going up and down the East coast were as short as 5 minutes. My longest stop was over an hour but was caused by my own doing... Since it was a food stop. The benefit of driving in this fashion is also that it is more relaxing overall. I didn't feel stressed to get somewhere and stopping gave me time to rest from the road driving.
This was precisely my experience driving from DC to Florida. The family needed a bathroom break every ~2 hours, we timed them to coincide with superchargers, and by the time we were done the car was ready to reach the next charger. Some of our stops required more charging time, so those were lunch or dinner, and by the time we finished each of those we had a nearly 100% full battery. It worked out pretty well, and for the entire ~2500 miles we only had to wait for the car a total of ~30 minutes (out of a cumulative ~8 hours of supercharging).
I used to take 4-hour trips from DC to NJ and arrive exhausted, sore/tense, and in a bad mood. On our Tesla trip to FL, I did >10x the driving, and although I was tired at the end of each travel day, I remained comfortable the whole time. And with the Tesla, those 4-hour trips to NJ are no longer exhausting either.
