> Sure, and the owner's test involved snowy conditions (Broder's drive had clear weather), which generally increases energy consumption. So what? If they repeated the test, but put the car in a refrigerated warehouse at 10F overnight in Groton, would that satisfy you? Can you propose any test that would satisfy you? I don't say this to be combative. It just seems like the goalposts keep moving.

The goalposts haven't been moving. That was the single most important factor of the entire trip on battery life. Period, end of story. Any attempt to "replicate" the experiment without replicating the actual event that led to failure (leaving the car unplugged overnight in sub-freezing temperatures) is missing the entire point.
