Short is relative and he assigns motive for her reason for taking off. She was fleeing the cop (from his POV). That was where she blew it. She had no logical reason to flee after waiting.
The lack of common sense was on her part.
It doesn’t matter whether she waited three minutes or three seconds. When he walked to his car to run her plates and write her a ticket, he clearly didn’t give a damn whether her father was dying or not. It’s clear to me that he likely did believe her, that she really was coming to the hospital, and he *still* wanted to ticket her and run her plates (hoping for a warrant out on her so he could make the big bust? — yes, I know dispatchers, too, and you’d be surprised how many officers here pull people over for literally anything they can think of just so they can run the plates). Either way, if he believed her it only proves the point — he was bereft of all humanity. Write the ticket, maybe find a warrant, and get the bust. “TEACH THAT SPEEDER A LESSON, DAMMIT! DOES SHE THINK SHE’S SPECIAL?” I know the type — I’ve met the type, many times (not as someone pulled over but simply because I know quite a few officers). Someone who had enough sense to see that she was hurrying to the hospital might have let her off with a warning — but I guess teaching people a lesson is more important than having any humanity anymore.
