I am not convinced it would, TBH.
If people don't want to buy the cars, then the production line will eventually have to stop, permanently. And you get zero compensation for lost revenue.
If a production line is hit and has to close, then insurance will compensate part of the damage and after a few days or weeks you can be up and running again.
The gunk is just compacted dust from the desk surfaces.
Perhaps a bit gross, but it's mostly stuff you're breathing in daily, just now visible due to being compacted.
Super gross to me would imply something like bodily fluids or other biohazard.
Am I missing something?
