Free Path Vehicle
A fleet vehicle that moves over a free path.
Everything a modeller uses -- assignments, batteries, failures, the manifest, every statistic -- is on FleetVehicle and is the same as it is for a vehicle on a guide path. What is here is the body and the three answers a substrate owes: how to move it while somebody pushes, and what to record about where it stopped.
Parameters
how far apart the decision points of a journey are. It fixes how quickly a breakdown, a flat battery or a redirection is observed, and it is ignored where the spatial model cannot say what lies between two places -- there a journey is one step and the vehicle arrives before anything can stop it

Properties
Functions
Nothing is held and nobody is obstructed. A vehicle stopped on a free path is in nobody's way, which is what a free path means; a policy asking isObstructingNow is told no, and a policy that tows only obstructing vehicles will correctly never tow on this substrate.
Builds the interruption for a flat battery. See failureInterruption.
A tow along the free path: the same geometry an ordinary journey uses, at whatever speed somebody is pushing it. The speed is already set on the body by the time this is called.
