This assumes that you always have a conveniently located gas station which takes no additional travel time to get to. Where I live, I do have a corner gas station on my route, HOWEVER, the Costco (which offers a substantial savings on a tank of gas) is 10 minutes away. This means that I am often spending 20 minutes in travel time, plus another 5-10 minutes waiting for a pump (dependent on the line), before spending 2 minutes to fill the vehicle. Being a 2 vehicle household, it's not unusual that keeping the vehicles fueled for our daily commuting wastes a combined hour+ per week. The ability to plug in at home would be a dream! A 20+ minute rapid charging penalty on long road trips is virtually meaningless to me, since every time I stop for gas on road trips right now, just getting the kids out to stretch their legs or go to the bathroom is 15-30 minutes anyway.
