So yesterday I finally drove the wife's Model 3 on a road trip. Loved the enhanced auto pilot and finally got the hang of resting my hand on my knee, loosely having my hand around the wheel and just pulling towards myself on the steering to stop the hands on the steering wheel warning. The issue I found was that 3 times during the trip with auto pilot off on city streets I noticed a very fast vibration through the steering wheel like going over a washboard road. I was on perfectly smooth paved roads. The vibration felt like the steering motor oscillating, a high frequency oscillation lasting about a second or so. I am an automotive mechanic so the first time it happened I just thought it was the road but decided to pay closer attention just to make sure because it was much different than a rode vibration. After the third time I knew something was up. The third time I decided it was steering motor oscillation for sure which leads me to believe it is software issue. Anyone else notice this? Hopefully it's logged into the software so Tesla can see it.
