You look at your rear-view mirror and see a truck coming at you VERY fast and he's VERY close.
Truck driver haulin' at 100mph. He sees your car. He wants to play bumparse with you rinkydinky prius.
You turn your head around to look back. Indeed, there is a big #$@ truck back there and getting mighty close.
You turn your attention to the road ahead. WHATS THIS? OH NOES AN OLD LADY IN A WALKER IS CROSSING THE INTERSTATE! SHE'S ON YOUR LANE!!! YOU WILL SQUASH HER IN 4 SECONDS!!!
You swerve to the opposite lane to avoid the lady. She curses at you as your prius clips her purse off her and screech to a halt on the parking lane.
Old lady turns her head and sees the incoming truck.
Truck driver sees your prius suddenly swerve out of the lane. Hears a 'thunk' sound.
Old lady gets squished by Truck.
Sysmessages:
(Prius)
Host: You have Landed.
(Truckdriver)

(Oldlady)
Host: You have collided with Truckdriver.
-----------------------------------------------------------------------------------------
Its all about perspective on your end.
You in the prius saw the old lady and she saw you so you managed to swerve out of the way and in her view, saw you swerve out in time. Hence on your end (front end) and in hers, you did not hit.
Truckdriver did NOT see oldlady and ran her over and kept chuggin' after you. On his front end oldlady was not registered as a collision yet gets credit for kill because you caused it on her end.
Oldlady saw your prius coming at her and then swerve out of the way hence no collision for your prius and her. However she did turn around and see the truck coming so she became a grill ornament.
