It is by no means a constant occurrence. I've edited my original comment to disclaim this as you seem unable to assume good faith about any of this. It has happened only twice, both times with a fairly wide margin where human intervention could have occurred should it have been needed (it wasn't). Changing lanes is a type of turn because you _turn_ the wheel to change lanes. You also might turn 45 degrees in a roundabout, or 90 degrees at a stoplight. They are all turns. I'd agree that it's an assumption. Though your assumption that the distance is closed _rapidly_ is also just that - an assumption, and one made in bad faith despite my efforts to correct it. The mere act of being in a car on the road involves dozens of assumptions made every single minute about the traffic conditions. Very little is known for certain, ALL maneuvers are to some extent based on assumptions. This conversation is no longer productive, thanks for your participation anyway though.
