In the original Beverly Hills Cop, Axel Foley sabotages an unmarked police car by inserting a banana into its tailpipe. According to what happens in the movie, it looks like doing so causes the car to stall as soon as it starts.
Does that really happen? Does the banana truly “disable the unit” (to use the phrasing spoken by the frustrated Police Chief). I’d think it would be more likely that you’d kill the occupants by carbon monoxide poisoning.
