I was stationed in Montana for the Air Force in the 60s where it would get down to -30F for a week at a time. We too had to keep our car batteries inside our barracks if we wanted to start our cars after work, All except one VW bug, it seemed to start no matter how cold.

Seems to me that the wind direction will be somewhat obscured by the mass of the wind follower, that is sure to overshoot and oscillate to some degree. So not sure other then some 'averaging' code one could count of wind direction being anything but just a relative measurement. Same might be the case for windspeed impulses.

Gotta love the bugs. My '59 was indestructible.

The wind vane does have significant momentum. That may account for the way it dances around in a gusty wind. I'm going to have an Arduino down on the ground managing it and the other sensors. I can keep a data base and play with the numbers a bit.

Probably because the battery is underneath the back seat.  Which is all sorts of fun when the bug rolls over.
