Yes, most of it is in cruise control around 38mph, I stop the car from going over 40 by turning off CC at the crest of a hill and using L to slow the car down some briefly if hill assist is not holding as tight depending on the grade. Also on the uphills I turn off CC and limit power to 1.5 to 2 bars tops and let the car lose speed, no more 2.3 bars with CC, allowing the car to lose some speed makes me go further than being determined to climb the hill at 38 minus whatever eco cruise lets it drop. I'm ok with letting it slow down into the low 30's the battery % drops less after the hill. Then I use the downhill on the other side to get back to 38 at 1 bar power.
At night speed is of the essence is some way, as the headlights are burning battery and you want to get there, so I try to go 38 as often as possible. Going over that speed drops the cruise coach bar, and you end up with a driving score of less than 99. Also brake score needs to be 100 or 99% at a minimum (only one little stopping mistake allowed), any bigger mistake than that will drop your driving score, i.e. a 98 brake score will lead to a 98 driving score.
Hope that helps you become a better driver! Depending on how you do it, you can go 18 miles on the battery or 34 miles. I remember telling my wife yesterday evening we've gone 18 miles and I still have 1/2 battery left. I enjoy the reward of making it, last night was a challenge at night, I had to soak up every electron of regen I could, and as you can see I got into the hybrid battery just 1/2 mile from my house climbing the last hill home.
