I'm not quite sure what you are disagreeing with, but I assumed your original comment was about parking your car and leaving the AC running while you go shopping or whatever. As I said, you can do this with a Prius but it's effectively the same as leaving the keys in the ignition as the car needs to be in "READY" mode, which means everything is running (at least on my standard 2010 model - maybe the PHEV model is different) - if you can get it, you can drive away without needing the key. You can also start the AC from the remote, but it cuts out after 3 minutes or when the battery gets low - it doesn't use the engine to recharge it.
