Meh, that's just a rule OCD public façade since people are watching and so kids don't learn bad habits and get killed by cars, but privately many Germans are more than willing to break rules if it benefits them and nobody is looking and won't find out about it, just that they don't openly talk about such things since the Germans are super private about their personal affairs and finances, and you also won't hear about such things if you only hang abound in bubbles of SW devs and other repeople with corporate jobs in big cities.

My favorite is them not paying taxes on cash earnings. Cash is king for a reason in Germany: many small businesses, self employed or side hustles love doing business in cash since they can dodge the tax man and pad their incomes with untaxed earnings.

Please tell them that "rules are rules" when it comes to paying their taxes on cash earnings and they'll tell you to shut up and piss off because "everyone is doing it" and "it's always been like that".
