Autopilot functionality: keep within normal lane position when markings disappear on one right side (mergers)
Autopilot needs to keep close to the left lane markers on freeways, especially when a right-side lane entrance comes up. At the end of the lane entrance merger, the lane markers disappear (on the right of the Tesla). Currently, Autopilot simply swings the vehicle into the middle of the two merging lanes. This is very dangerous, as human drivers often use the unmarked region to accelerate past the freeway traffic (passing on the right). I always have to disengage Autopilot at these points on the freeway, or move to the middle lane (pending traffic congestion).
