I am on a 1200 miles road trip across few states and am finding that many highways do not have continuous lines on exit and entrance ramps causing the car to make dangerous shifting to center within this almost double width. One one highway, I had to disengage autopilot at almost all ramps. The result is even more dramatic when you let the car center when you reach the end of an exit ramp as the car would either jump to the left or aim to the highway’s shoulder. Can somebody give me one reason why on highway speeds, the software is not using the left lane as a guide (or the GPS information) to prevent those dangerous shifting. Also, if you want to take the ramp, you will likely disengage the autopilot as the blinker would not work.
