What if users were able to input a speed fluctuation value that autopilot used to increase / decrease speed on hill ascent / descent? For example, I input a speed fluctuation value of 5 MPH and autopilot allows the vehicle to lose 5 MPH on hill ascent and gain 10 MPH on hill descent. I live in StL MO and there are lots of small hills everywhere I go. I've used this approach manually around town and can greatly increase efficiency of my M3. I imagine software could do an even better job with even less speed fluctuation. Thoughts?
