So true... and by the same token, there isn't any point in expending extra effort at maintaining any particular temperature either.
After all, the most common way to make this sort of transport would be to put it in a bucket and put a lid on the bucket to avoid spilling the water in your car (don't want a trunk full of tank water from slaming on the brakes to avoid running into the idiot that cut you off).
But if you start trying to add a heater to the mix, you would likely loose the "protection" of having a lid on the bucket.
BTW, the various numbers are interesting to know (because before this discussion, I didn't know them)... but the only ones that are important for this particular discussion are 32 and 120... keep your water between those two numbers and everything will be ok for the car trip home.
