Nah, it is just that once I saw that you were the King of Conflation, misrepresenting what fueleconomy.gov and the Volt manual said, I didn't have the desire to continue to parse the text for you. You took one sentence that applied to 3 to 4 mile trips and applied it to the entire article. You also took some suggestions at the end of the article that help with fuel economy in cold weather to mean that the initially stated fuel efficiency drop percentages were “predicated” on not doing those suggestions. When in fact, that very section starts by saying, emphasis mine, “You may not be able to completely mitigate cold weather's effect on your fuel economy, but you can do some simple things to help your gas mileage.”

The website you mention, gm-volt.com, is not run by GM but is actually a fan-run site. They could still be correct, and if so I would be wrong about the battery cooling system coming on when unplugged. Here is what they say in one place:

What happens if the Volt is parked in the hot sun with ignition (power) off and NOT plugged in? This would be the scenario for many Arizona workers that park their cars in full sun on a black asphalt parking lot all day. How hot will the Volt’s battery get?
In order to determine, Volt was parked for a day in full sun. Results of this test are presented in figure 5. We see that the Volt’s battery is extremely well insulated. With cabin temperatures soaring to 115 F and ambient air temperatures going to 99 F the Volts battery only reached a maximum temperature of 90 F. Roughly equal to the upper limit during active thermal management during charging shown in figure 2 . We also note that there is NO ACTION taken by the TMS in this case.

Though elsewhere on the website people say that it will come on when unplugged if you have at least a certain amount of battery charge.

Regardless, that does not mean the manual says that you need to keep it plugged in when it is out in the sun. For the umpteenth time, it suggests it as a way to increase efficiency, not as something that is needed to prevent battery damage. (As the gm-volt.com post I quoted above indicates, even in 115 °F weather, the battery pack did not get over 90 °F.) Since you repeatedly conflate the text to say what you want it to say, and since you are invulnerable to correction, I'm not going to beat this dead horse any further. You can argue with thin air from here on out.

Regarding Willie Green, I had to look him up to see what you were talking about. I'm not too impressed with passenger trains myself. They are one of those things that sound good in theory but oftentimes don't work in the real world.
