What happened here? Hint: The light green Bastion was not involved. I'm not sure how hard this is - so if I have to I might add more hints. I've always wanted someone to do this so I could look at them, so now I'm doing it just in case someone else would be interested.
The truck hit 2 of the other 3 cars, but did not hit one. Thanks! I had fun making it The trick is to sort out which were moving, and which were parked, as well as direction of travel.
