Its 26F outside and I just remembered to take my 12v electric lap blanket I
got for Xmas with me.
It made my lap as warm on the top as from the heated seat from the bottom.
The blanket is $20 or so from Walmart and I like it.
It is made to pretty much cover the legs, lap and torso of a passenger, but
I left mine folded over in to a quarter (4 layers of heating wires) which
then fits nicely on just my lap. (and got 4 times as warm).
A few minutes Into the 15 minute trip, I was very comfy.
Every EV ownwer should get one of these. The VOLT convenience outlet on
the dash shuts off with the Ignition, so I can just leave it plugged in and
