Since I first picked up my Model 3, I’ve had some AP issues at a series of intersections I pass every day on a divided state highway.
At one of these intersections, the road turns steeply left just as an on ramp appears on the right, so the car ends up pointed dead on into a what appears to be widening lane with new lane markers popping up straight ahead. AP has repeatedly bailed at this point, throwing up the red “take control immediately” along with an audio warning.
At the second intersection. There is a lengthy on ramp with lane markings that end after a short distance. Other such on ramps have been well handled, but on this one the AP has consistently seen this as a widening lane and swerved the car right to center it in what it sees as the new, expanded space. Depending on traffic, I’ve sometimes needed to take over to prevent this.
Both these behaviors continued under 24.4. However, after installing 28.3.1, the car twice sailed through these two intersections with barely a bobble. In both cases, there was some slight movement right and left, as if the car was hunting a solution, but it was inches, not feet, and I went on without getting a beep or having to wrench the car back into the lane.
Has anyone else noted similar improvements?
