I live in Australia, which is culturally the polar opposite of Germany[1], and you'd get a similar response here. If the police saw it, you'd be fined at least $500, and risk losing your licence.

1: Australia is very egalitarian, rather than hierarchical. Pragmatic, rather than bureaucratic. Australians are direct and emotive communicators. Spontaneous planners, etc. etc.

Risk/cost ratio? A pedestrian acting irresponsibly can of course do a lot of damage, but the likelihood of killing someone is much lower than if a vehicle is breaking the rules.

There is a huge difference between someone being annoyed by some thing based on how it affects you and that thing just so happening to be against the rules vs being annoyed by a thing that's of no consequence to you for no reason other than because it's against the rules.

Regardless, I don't share those values. I have stared into the abyss of what people who praise conformity and the common good will do to a municipality if given free reign to regulate it's minutia and I do not want. My neighbors on one side blast music in a language I don't speak until a couple hours after my bedtime most nights and the neighbors on the other have barking dogs. I don't even notice them anymore, same with the nearby highway noise.

Fine then. They drive the speed limit in the left lane or whatever. Point is that the people who advocate for the rules in obscenely trivial situations when deviating them them is in fine taste tend to be drawn from the pool of "robotic rule follower with no extra thought given" type people. Which has the side effect of making them consistent with what they preach.
