A fair point (tech advances) but a piss poor comparison. One is extremely convenient to use. The other... I'm not even sure it's really all that convenient unless you have arthritis and have a hard time opening a gas cap. Ask my wife how much she loves just leaving her key in her purse. Ask her to go back to using a key. That's a whole other level of convenience that, at least in my opinion, is in another league compared to... a gas cap. And apparently you need to learn how to use cap less by waiting xx amount of seconds? This is convenient?
Few people are "techier" than me. I am all for technology... but a gas cap, imo, doesn't need improved.
Again, I fault no one for liking this feature. But you can't compare it to keyless. I suppose I would compare it to an automatic lift gate. Another feature I don't care about. hehehe
