Collision detection - how does it work?


i looked around the car and I didn’t see anything obvious.
I drove the car yesterday for 10 min and i didn’t see this screen. My phone app didn’t have any collision alert also. And this nov12 is 2 days ago.
questions,
1) is the picture in the screen suppose to tell you where the collision happened ?
2) why is it reporting it 2 days later ? There was none yesterday
3) after I click on no, I could not find this message anywhere anymore. Is there a history somewhere?
thanks
