So driving home today I was on a 55mph stretch of road that I take each way to work each day. Even though it is a 55 zone most people travel at about 75 or 80 (yea yea yea). In the past autopilot has had no issues at 75 on this road but today (@ about 6pm so still bright and sunny, completely empty road and straight) the car just suddenly slowed down to 65. No error message about "5 over" came up (and the car was doing more than 5 over). Has anyone run into anything like this? I found a similar video on YouTube:: This was obviously night and may have been that he camera could not see far enough, but mine happened in the daytime... Thoughts?
