Ah the old Costco gas line, how I don't miss that. My old G37 couldn't quite make it a week to refill. All three Costco's in my area were about 5 miles out of the way round trip, but typically 10-30 cents cheaper. So I would go, and I would wait in lines much like the one pictured. It would be Thursday after work when I just wanted to go home, or Friday morning when I was already running late and I'd just stop at the Shell station on the way (who had an extra credit card fee, and Premium was 30 cents more than regular per gallon. $70 was a typical fillup, about every 5 days. So when people tell me plugging in is a hassle I see it just as an earlier poster does, code for I can't afford a Tesla so I'll rationalize that getting gas is better. The savings in gas, registration fees and maintenance make my Tesla cost the same to own as the G37 even though it cost $20k more upfront. That's the argument that got my wife to sign off.
Supercharging, which I do not have, probably needs to be faster. 20 minutes compared to 30 is a great improvement. I know when we drive from PHX to SD, the last thing I want to do is stop for a long time. It was always a challenge to see how quickly I could gas/go and get drive-thru. But Supercharging is most certainly not free, it's prepaid.
