I love my clarity, but I'm fast falling out of love now that I've experienced 30mph driving with the engine on. A good chunk of my commute is on 30mph country roads. The car is so dead silent, and then comes the engine whine. And it's not a consistent whine, it only really gets noisy when the power meter is 2 white notches up. That's some sort of threshold for high revs. And then it stops after a few seconds when it's below. But it's nearly impossible to avoid going 2 notches up. So I wind up with, peace and quiet, whine for 8 seconds, peace and quiet, whine for 8 seconds, etc.. and it's driving me crazy. Has anyone else experienced this? Any tips other than saving my battery for when I'm on these types of roads?
