No sensors on Q7 "sees" so far as 300 yards

That is very true, and 300 yards is 3 football fields. But I think sometimes presense acts wierd. For example a few posts ago I described how it came on for me (never had before), on a clear road. Never know what all data points the Q is processing

Nothing is perfect. I have had 3 times glitches with pre-sense, but always with rear one, not front. Front pre-sense functions perfectly so far.
2 times with parking, going backwards, pre-sense sensed something nonexistent. And once standing at traffic lights, pre-sense pulled back seat belt quite fast and strongly. That was most unpleasant experience.
Front pre-sense is a bit more sophisticated than rear. It combines data from 3 sources, 2 radars, 6 ultrasonic sensors and camera. There are a lot of data that have to be processed and analyzed constantly.

So my Presense finally worked! Some idiot was making a very slow left turn ahead of me and as I was starting to go around him from the right, Presense kicked in, chimed, slowed me very briefly but sensed i was moving out of his way and so it let me keep going

Glad to know that mine works!!

I've seen the triangle a few times, but the car has never auto braked for me. This usually happens when the car in front is turning right.
