So I watched this film maybe 10 years ago on disc and do not remember much.  The quality was like 80s-90s (but not certain) and the whole plot was this group of older siblings who were surviving or running away either from zombies, mutants, or evil henchmen.  I am certain that one of the final scenes was in the middle of a ghost town and the sister had crossed the street on a red light and the brother said “stop its red” and she said “who’s gonna hit me” (it was a ghost town) but then a car came speeding down. It didn’t hit her and she got in the car but it was supposed to be ironic.
