....and if it is a BMW it doesn't have signal lights.Just because someone has their Blinker on doesn't mean they are going to turn. I wait until I either see the vehicle slowing down to turn or they are already starting to turn.
[high horse]As an original tester (as I'm sure all other know to) you MUST take over as your car makes that kind of mistake. That was a clear case of it making 2 mistakes. The route was to go straight but it tuned instead. The millisecond the wheel started turning was the time to disengage. As a long time tester I see these type of edge cases before they happen and I'm in full on monitoring mode.
Oddly I have wondered about the above IF we do get L3/4. Will I be able to sit back and let the car drive after a few years of being "on the edge of the wheel/brake" and taking over in a near instance whenever I sense "trouble coming".
