There's something Falling Down-esque about this cop's nervous breakdown in Grand Theft Auto V. He almost gets the squad car out of the driveway with a multi-point back-and-fill move -- but then ... he just loses it.
Tim Burke over at Deadspin captured this; it happened in the open world after finishing the heist mission Blitz Play. He went up to Devin Weston's mansion, got Solomon Richards as a mission-giver, went outside and found this Los Santos County deputy trying to get out of the driveway (apparently he was pursuing Michael when the previous mission ended).
You can see the drivers slowing down and shaking their heads as the deputy destroys his car and ultimately gives up. Tim decided to follow him -- up hills, down them, through a ravine to the beach, where the cop starts swimming in circles, draws his gun and disappears.
Who knows why it played out this way. Maybe Rockstar Games gives you 10 minutes to either kill or ignore a cop before he whips out his sidearm and teleports the hell out of there. Nervous Breakdown Cop, whither goest thou? Maybe an appointment with Dr. Friedlander would help you.
