Factual error: Bobby picks up a gas nozzle at the gas station and squirts gas at the bad guys. Gas nozzles won't activate without payment being made first.
Continuity mistake: After RVD is shot by the lone motorcyclist he goes home to take care of his wound. You can see that he was shot in his LEFT shoulder. When he goes to the bathroom and takes off his shirt, the wound is on his RIGHT shoulder. After bandaging up his wound, he finds his wife bound and gagged and his daughter has been taken. He goes out to the garage and you can see his LEFT shoulder is now bandaged. (00:58:50 - 01:01:55)
