I mean your law abiding speed … they officers for some reasons did not like being slowed down.
only been pulled over a few times in my life, but every time it’s been this kind of thing, usually late at night, Each case had almost identical features foremost of which is a rude surly police officer blatantly lying.
I think they are checking for intoxication but could not admit they were wrong about when they stopped so came up with silly reasons.
Sometimes zombie bureaucrats need to be seen to do something in order to justify their position. I have no doubt that some want to be seen as doing something so that they can either be seen as promotional materials or be seen as “pro-active”.
