I'm curious if it is possible to create a cruise control that works not only on speed but also takes into account whether you need to conserve battery or not, like CC2 or something. The area I was driving in this past weekend is very hilly, which is never friendly to any cruise control. I ended up driving watching energy usage more than speed because the cruise just ate up my range. I didn't drive slower than the speed limit but ended up several times going well above! My right leg was so tired by the time I got home, but I 'picked up' 5% battery, from 6% up to 11% by the time I got home. I was thinking to myself that it would be great if there was a 'conserve battery' cruise so I didn't have to concentrate so much on how much pressure I was putting on the accelerator. (My husband, who was driving his S on the same route, texted me, "Show Elon you trust the machine!" because I had wanted to stop at a destination charger to grab a little more range. If I were a tweeter, I would have tweeted that. Kind of funny now.)
