Wow I miss regen braking! Nashville has been cold - we get a spell of very cold once or twice a winter and we are in one now. Having taken delivery in August this is my first winter with the car. Really miss regen. My trips are short each day - yesterday (according to Visible Tesla) I had two 8 mile trips (work and back) and two 3 mile trips (going to the greenway to walk). Never saw full regen. Just lamenting the fact that I don't live in a regen friendly climate like La Jolla or Miami.
