My trip was from Cincinnati to Williamsburg, Virginia, so the drive went through the mountains of WV and Virginia, with most of the trip between 60-75mph. On the drive there I tried to keep some ev juice available for steep inclines which meant I was doing a lot of switching between ev, hv, and hv charge. On the drive home I lapsed a bit at the start and used up my battery pretty quickly, which brings me to my first quibble: HV CHARGE DOES NOTHING AFTER YOUR EV RANGE HITS 0. It doesn't matter how much you run in hv charge mode, nor how much downhill driving you do, your battery meter doesn't go above the two bars. Why is that? My other quibble isn't drivetrain related, but rather a complaint with the head unit. I was traveling with my family and I wanted to run Google Maps with Android Auto, but I also wanted to listen to my stuff through headphones so no one else would have to listen to my stuff. Unfortunately, plugging in to the usb plug to run Maps requires bluetooth to be on so I couldn't use my bluetooth earbuds. No problem, I can use my traditional earbuds. Nope. If my phone is plugged in then sound is coming out the cars speakers whether I like it or not. Fine, I'll just unplug the phone and run Maps on my phone screen. Nope again. My phone kept starting and then crashing the Android Auto app, and each time it did it closed Maps so I had to restart my navigation over and over again. I didn't even want Android Auto to be on but I couldn't keep it from starting. This continued until I finally turned bluetooth off on the phone. Only then was I able to listen on my regular earbuds and have Maps running on my phone without any problems with Android Auto. As a final note I should mention that when I filled up with gas in the mountains of WV with a depleted battery I averaged 48 mpg on the drive home. Not too shabby! Also, on one particularly long and steep climb through the mountains I experienced the cars engine struggling to make the hill and I started losing speed towards the top. Also, my battery meter went from two bars to one, which I hadn't seen before. My 2010 Prius did the same thing on really long hills, though, and it is a smaller car than the Clarity. It only happened the one time. Overall the Clarity kept up very well, and the driver assist/adaptive cruise was awesome!
