Ok, so I had 14 miles left on the charge today when I left for a 72 mi round trip. As expected, battery miles ticked off, got to zero about 15 miles into trip and then the ICE kicked on as expected. What I didn't expect was the ICE miles remaining meter fluctuating so much and actually gaining miles, then the battery power kicking in for a bit, then back to ice, then back to battery, etc. I didn't use up anywhere near 72 miles off the Battery and ICE miles remaining tickers combined. What's up with that? How does the ICE software calculate? Does it "learn" as well? Why did it switch back and forth to battery power? This was not at stops or lights, this was while driving.
