Upon rescuing your wife/mother/girlfriend who has been held prisoner for month or even years, they will choose the moment of rescue to suddenly drop dead.
Any bad guy on the verge of death has important information to impart first.
Cars are always nicely positioned for you to steer easily around should you be chased.
Any vehicle having to jump a gap in the road will somehow get a lift as it leaves the road as if there is a ramp there to help.
When running away from a bad guy, always try to climb as high as you can
