Had an excavator run out of fuel while crossing a bridge. Thankfully because even on "vehicles stop when out of fuel" settings, an empty vehicle will continue its last task until it reaches its destination and it won't get stuck on the bridge.
However every single fuel truck suddenly started freaking out trying to reach it. So not a huge issue, just a weird bit of UI clutter that will clean itself up when the excavator reaches its destination and its a valid object for the fuel trucks to visit again.
Edit: Okay it just rolled itself over to the nearby fuel station instead despite being at 0 fuel.
