My car is pretty terrible at staying straight when one line disappears to allow for a cross road or an on/off ramp. Basically what happens is instead of staying 2 ft (or whatever) from the dashed line, it follows the solid line as the line darts away or something. Either way, it quickly jerks to the side (happens to both left and right).
It just seems the car needs to realize that if a line disappears, to follow the line that is still present.
