I'm totally with smkettner on this. There is nothing wrong with using a timer and also using a public charging station. I'm not going to reprogram every time, either. And there IS something very wrong about unplugging another EV just because you need the charge, whether or not the other one is done charging and whether or not he's on a timer. It's more than just illegal in California to unplug them, you are also making the other car subject to being fined (maybe even towed?) because that same law now makes it illegal for any car, including an EV, to be parked at a charging station and not be plugged in. Protocol cards are almost useless for this reason, although it might be smart to have a phone number or email so that if some idiot like TangoKilo unplugs you, he could (probably wouldn't) contact you to let you know so that you could go back later and replug. Even without the law, it is just plain wrong. I see no difference between unplugging another EV to charge your own and a situation where the power goes out in your house from a downed tree limb, so you go and disconnect your neighbor's main and attach it to yours leaving him without power. Sorry, you just can't do that. Like your home power, or the gas pump example given earlier, once you plug in the plug is yours until you unplug, period.
