Reduce maintenance when machine / vehicle is idle

Give maintenance discount on idle entities.

Was there not recently an update that made maintenance easier?
I like this suggestion but i don't want the game to become too easy. The way it was before the maintenance update was ok once you got the hang of it.

Humbly but strongly support this proposal based on many hours of playthrough observations. Not only because it totally makes sense logically, but also due to the risk of well-known snowballing collapse happening when maintenance production exceeds demand and stopping trucks temporarily - rather cripples things then helps, which is opposite from what the player would expect making it almost impossible to recover.
My proposal is to go like 5x times less in reduction on idled/paused trucks and buildings.

More like 20x reduction I think. If you don't want it to be too easy you can always increase/rebalance the "normal" maintenance slightly. It just makes sense that idle entities don't need maintenance. Could go all the way down to zero, if that's simpler to do.

Zero is unrealistic too. Vehicles corrode over time and do require occasional painting or replacement of some parts even if just standing somewhere. So reduction is better then going 0.

Have them be normal maintenance at the start. Research a outdoor car park that has maybe a 20% reduction if it is parked in there (they auto park if free space) then a further down the tech tree for a upgrade to an indoor car park that reduces the maintenance by say 50%. You could even have a 3rd tech item for a multi story car park. You could even have the tech be upgrades to maintenance building
