I have already extolled the virtues of Autopilot and how it has made my morning commute so much more enjoyable (see: How Autopilot has added years to my life.). One thing I'm noticing is it has been a complete 180 in terms of what actually makes me happy when I drive. Before Tesla I definitely was the type A driver, priding myself on shaving a minute or two by making smart moves on the freeway, going around "road hogs" in the fast lane etc. On long road trips I prided myself on driving continuous for long distances without stopping and maintaining a high average mph. Now I'm noticing that stuff like that doesn't matter as much. Maybe I'm getting older, but I think Tesla really has shifted my view of "reward" in different driving scenarios. Take for instance today on my commute to work, I was thrilled that I achieved the lowest avg watt/mile rating since I've owned the car for my morning commute. The difference in this lower rate was quite negligible in my overall range (and I have no worries about range anyway), with only maybe a 6 mile increase in my rated range, but I was far happier achieving it than getting to work 2-3 minutes faster like I used to. By the way, even driving majority of commute on freeway at 79 mph (37 mile commute, probably 8 miles local roads), with autopilot on during freeway drive, the watt/mi avg for entire trip was 274, even lower that EPA rating which I thought was done at a much lower speed.
