Traveling under AP in the middle lane of 5 lanes, relatively light traffic,
good lane markings, no sun glare, the car suddenly wants to veer
sharply right into the empty lane. With my hands on the steering wheel,
holding very lightly, I detected the jerk in the steering wheel, grabbed
the wheel tightly, and corrected, probably before the car actually left
my lane. Fortunately there was no car to the right, but it could have been
serious.
No, I did not accidentally signal for a lane change, or use the other
controls, but having my fingers actually very lightly "gripping" the
wheel (to feel what AP was doing) allowed me react very quickly.
So, nothing visually apparent that would cause the AP to swerve
or jog right.
What I did do, a few seconds earlier, is give a voice command "Drive Home",
and I think the route was being drawn (approximately then) when this
unexpected "jog-right" event occured.
So, just maybe, something in route calculation or drawing, or calculation
of the expected energy usage graph, might have monopolized some
resource that caused the AP to "glitch"? Only a maybe, I realize.
In any case, a warning of an event with a high "pucker factor".
