I have had the same thought about "idling" in the LEAF...oh, I am going to get CO poisoning. oh, I am going to overheat it. oh, I can't run the AC without the engine running. oh, I need to pass this car....will my little car have enough umph? oh, where are my keys? as I grope to put the key in the ignition and a million other ICE habits I am trying to break!
