I am carefully testing v8 in a variety of situations, and offer the following comments: on the AutoSteer specifically:
1) During my daily drive/commute, v8 works very well. I never get the lane wandering. In fact it seems smoother than v7.1 as it does not wander/hunt during crossing of intersections where there are no/limited lines. It handles these better.
2) During other drives on roads that I'm driving for the first time, and especially when driving a 'road less travelled' I get the unexpected lane wandering reported by a number of folks (when the lane marking are good enough that v7.1 would have been able to steer just fine.)
I speculate that the data fusion engine for AutoSteer, which takes inputs from the radar, side sensors, camera line recognition and the Tesla high definition maps (fleet learning) is now placing more weight (and perhaps incorrectly) on the Tesla mapping, which is sometimes poor (few Teslas having driven the road) or in some cases wrong, which causes the AutoSteer to unexpectedly drive out of the lane.
Do these obeservation match what the rest of the group are seeing? Is the 'bad steering' occurring for anyone on the daily commute rote with good markings (where the Tesla maps are expected to be good) or can anyone else confirm that the driving is worse on new routes/less travelled routes where the Tesla maps could be expected to be poor?
