Then I noticed going over the same road several times, that "in traffic" there was no noise, and found out that if I gently had my foot on the brake, that the noise went away.
A little poking, prodding and wiggling, and the culprit was found. It's the friggin brake pedal sensors. Added lube, problem solved.
Images attached to give myself some form of accomplishment over something this annoying, yet so trivial. And I was a bit bored. Colours for reference.
