The issue in Germany isn’t so much that infrastructure needs to be maintained but that a lot of the bridges were built more or less at the same time (after ww2) so they’re now failing more or less at the same time (at the end of their lifetime, no surprise there). Usually, a country doesn’t build so much at the same time, so maintenance doesn’t come all at once.
Sorry to be that guy, but this sounds like a cybersecurity nightmare. While everybody was busy to come up with schemes that make absolutely sure that only trusted sources can update a system to avoid having malicious players push their code to users, this one just takes any rando’s pile of whatever and injects it straight into the system’s core? Like, that doesn’t sound like a good idea.
