So, I've been on vacation for a week and only installed 7.1 (2.9.154) last night. I drove to work on my usual 20 mile route on CA-101 this morning. I've driven this route on 7.0 auto-steer maybe a hundred times, so I'm very familiar with its quirks and such. My main gripes with 7.0 auto-steer on this route were: it generally had a tendency to stay too close to the right side of the lane when in the left-most lane and it had trouble with dotted lane markers. My impression of 7.1 auto-steer this morning is that it ping-pongs all over the lane. In fact, if I was a cop watching it drive this morning, I would have stopped me for suspicion of DUI. The part that has me baffled is that the car seems to *know* it's doing it! I can see it literally hunting around the lane in the dash display. Am I alone in feeling that 7.1 has taken a couple steps back in terms of reliability?
