Well I can definitely say this doesn't exist in NY, there would be dire consequences for ambulance drivers if they did such a thing. Though that is not necessarily the case for other types of emergency drivers.

The story I have goes in line with this to a degree, and also happens to be the one and only time I have ever been 'protected and served' by the largest gang in the US-- the cops. Their motto of protecting and serving is mostly laughable, should be changed to 'we're here to harass you, waste your time, and ruin your day', lol.
In this instance my friend Mary and I were visiting NY city...and we forgot where we parked my car. We walked up and down streets and avenues for three hours until finally a nice cab driver recommended we try the NYPD. We were around eighteen at the time and clueless. Upon hearing our story, two young cops offered to help and next thing we knew we were in the back of a cop car, sirens blaring, as they drove the wrong way down one way streets until finally we spotted it. Turns out that it was a bad street in a bad part of the city, which hadn't been noticeable when we got there at nine in the morning, but ten at night was a different matter. Drug dealers and hookers scattered as we went past and the cops told us how lucky we were that we hadn't chosen to walk this particular street while looking for the car. They also told us where the safe places to park were should we decide to come back for another round of 'foolish tourists". And while I was extremely grateful at the time, looking back I know they only helped us because we were cute young white women, that most people would have been SOL and on their own.

I was recommended a story recently and the author posed questions to natives of the Philippines that you might be able to answer or know someone who can: https://steemit.com/conspiracy/@samstonehill/my-amazing-father-was-born-100-years-ago-today-a-story-of-us-corruption-and-betrayal
