What has been your experience with using Autopilot (including the self-steering) through the construction zone on I-95 through Needham and Wellesley, from Highland Ave. to Rte. 9? I have used it many times over the past year. In fact, I try to always use it. I figure that the lane alignment has not changed in many months, so the system should have it down pat. I have found that it even works very well on the northbound side where the lanes split, despite the rather erratic lane markings as you exit the split and as the road curves to the left. My one concession is that I reduce the set speed to 50 or so if I am in the left lane that splits off by itself -- that is a narrow, bumpy stretch and I figure there is no reason to be too crazy. (Plus the traffic normally limits my speed anyway.) But yesterday I had a scary moment when traveling southbound, just south of the Rte. 9 overpass. The car told me to "Take control immediately" and it looked as if I would hit the Jersey barrier on the left if I did not do so. So I took control and stayed away from the self-steering function until I was heading up the hill towards Rte. 135 in Dedham. I have noticed in the past that sometimes the Autopilot seemed a bit shaky in the left lane traveling southbound, especially in the stretch just after Highland Ave. where the road is curving to the left. Maybe it was the proximity of those Jersey barriers. And I noticed yesterday that the barriers are new -- they look different,as if they are polished metal -- is that possible? Anyway, curious what others have experienced in this area. I was a bit concerned after the system told me to take over yesterday.
