It is actually an insurance kind of thing as far as I understand. I've had plenty of cases where the bus couldn't continue due to being in a traffic jam, and people who would have happily get off the bus couldn't either.
Whenever something convenient in germany is not possible, you can bet it is a insurance thing.
And the insurance conditions are based on DIN/EN, VDE, TÜV and others. If you have bodies that create rules, they will never stop creating rules because it is their job to create rules. Something that started great to reduce unnecessary harm became a red tape monster slowing down everything.
Nobody gets elected or paid to reduce that in a sane manner (not: Chainsaw, Doge)
Leave the windows leaned open so it cools down in the office over night? Impossible due to insurrance. Somebody dies from overheated office and you want to sew the insurrer who enforced this ridiculous rules even on the third floor.. impossible, due to..
But it just goes to show how idiotic this culture of strict adherence to rules can be. I've been more than once been forced to sit on a bus for 10+ minutes, with the bus literally stopped by the sidewalk, and the driver still wouldn't budge when I said "I can just walk from here".
It's feels worse than talking to a robot. At least I know robots have been programmed.
30 years ago, when the train broke down, you got a clear statement what happend and what will happening next. Nowadays everyone is treated like a small child. They just tell the obvious leaving the people hanging in uncertainty hence people get mad and question everything without understanding the cause (because they don’t get that information)
