Repair
Repairs a broken vehicle where it stands, and leaves a flat one flat.
The default, and it is the whole of what the subsystem did before repair became a procedure: a failure costs the drawn repair time and nothing else -- no technician to wait for, no walk to the vehicle, no decision about whether it is in anybody's way. Every one of those is a delay or a branch a modeller adds by writing their own policy.
Doing nothing about a flat battery is not an oversight. Charge is a function of the odometers and no amount of standing at the vehicle changes it, so the only way back into service is to reach a charger. A policy that wants that must tow; this one does not, and the vehicle stays where it stopped for the rest of the replication.
