Character mistake: When Johnny Blaze plans on jumping the football field he says he is jumping field goal to field goal. The movie says multiple times he is jumping 300 feet. End zone to end zone is 300 feet. Field goal post to field goal post is 360 feet.
Character mistake: After Nicholas Cage jumps the line of trucks and lands on his head, his team race over and immediately pull off his crash helmet to see if he's OK. Anyone with first aid training or experience of crash victims would know to leave a crash helmet in place, as it could cause further spinal injury to pull it off. The helmet should only be removed if the victim is not breathing, and in other cases should be left in place with just the chin strap undone.
Answer: The movie doesn't show how long the effects of the Penance Stare last. I have Morbius #1, in which Ghost Rider uses his Penance Stare on Morbius, who recovers from it relatively quickly. I don't know definitively because I haven't read very many Ghost Rider comics, but the duration of the effects could vary depending on how much remorse the person already felt for their past sins, or how much their own super powers allow them to recover from it. From what I understand, the Penance Stare doesn't work on the Punisher, as he feels no remorse for the people he's killed. It also had no effect on Deadpool, as his greatest victim is himself and it actually caused Ghost Rider to revert to his human form when he tried it on Deadpool.
