Yesterday evening my wife arrived back home with a 1.5 ev estimate remaining. We thought there might be a chance that I could drive it to work the next day to charge it (we have not installed our EVSE yet) without starting the ICE (but if it did start that would be fine since it had not been on for weeks and might need it). This morning the EV range showed 0 (it was a little colder than the evening but not remarkably so). But it did start to drive without the ICE. And here is one of the interesting parts. The curved bar over the speed on the dash that gives you an idea at how much power the ICE will kick in was very pessimistic. It was on eco (it's always on eco). The sold part of the bar (EV for sure) was less than a tenth of the length. But I live only 2 miles from work and on slow roads so I took it easy and stayed on EV. Then starting from a stop sign after about a mile of driving, the solid bar was gone and the ICE kicked in. And here is the other interesting part. After a half mile of driving with the ICE and starting after another stop sign, the little solid piece of bar was back and the ICE was off. It stayed off for the last half mile which included a climb up a four story parking deck. With the solid bar as short as it was I could not reach much more than 25mph, but the roads I was on were suitable for that. Nothing good or bad here, I just found it interesting. I am still enjoying leaning about the quirks (features) of the Clarity.
