Any time the obvious meat computer-killing AEB/FCW bug was not active, 10.3 seemed more competent than 10.2. However, even with those improvements, I hope Tesla will quickly prioritize:
- near-center driving on residential roads without lane lines, even if there are no parked cars on the sides. It basically plays chicken with oncoming traffic. yes it will correct without colliding, but the oncoming car doesn't know that. After watching one car swerve and stop, I felt obligated to disengage anytime oncoming traffic was within a few hundred feet.
- Drifting well left of center at intersections without lane lines. If you let it do its thing at such an intersection, people cannot pass in the opposite direction.
- Swerving left when merging on the highway. I know this is a long-standing AP bug, but it's still a frustrating fail in an otherwise intervention-free drive.
On the plus side, I had stopped emergency vehicles on my side of the road in my neighborhood today. 10.3 gave them a wide berth.
