This is key. People don't care how long the total process takes. People care how much time they spend standing around with nothing to do, feeling bored. A 15minute charging stop can FEEL shorter than a 5minute gas stop if you have to stand there and hold the gas pump handle the entire time vs walking away from your car and going to buy a snack or (in the case of Tesla, this was a excellent idea and not just a silly easter egg) sitting in your car for 15minutes playing a video game. My wife and I will happily spend 30minutes playing with the music synthesizer in my Tesla and forget that we finished charging after 20minutes.
