I was just using CC on my drive back from a leisurely run to Mojave to get out of the house, enjoy a beautiful drive with the winds blowing more than usual in the high desert and do some Covid-safer grocery shopping out at their Stader Bros.
160 miles roundtrip, but I was using the heater and the trip north is uphill after some preliminary driving first.
I wanted to do the roundtrip without any 3rd party charging and I noticed that the GOM said 80 miles available as I left for my 80 mile trip.
The key is to make it to Agua Dolce and then it is downhill all the way to the hills before the San Fernando Valley, where I live.
So to keep my "hot" foot from running down the battery too soon, I drove in the right lane with the 18-wheelers and CC'd around 55 MPH in L mode
When a truck ahead of me is driving slower than I am , I use the "-" button to decrease my speed and then the "+" to pick it back up again.
If their rate is too slow and I need more deceleration, I use the paddle to get out of CC and drive manually.
Probably obvious, but when in CC and you use the accelerator to go speeds in excess of your set speed, once you remove your foot it will slow and then settle back to the set CC speed. In other words, while braking will turn off the CC, accelerating will not.
MyChevy app said I had 10% left in the battery when I reached home to my Clipper Creek 240v/20A charger.
