Preconditioning, the extreme cold in Chicago, charging. And a little experiment

As I listened to the story out of Chicago, I started to realize what we had was a user experience problem.
Yes, the info about how to charge your Tesla is in the user manual. But that doesn’t mean it’s the users fault. The cars are designed to precondition if you route to a charging station. But if you don’t, you have to wait for the batteries to warm up
I also performed a small experiment on a rechargeable AA battery to demonstrate how this works.
