What is the point in mapping roads where the gritter drives, if it is 
not gritting there? How is that useful for anyone?
It is useful for drivers to know whether or not a road will be gritted, 
but it doesn't matter what order the roads are gritted, or where the 
truck goes before or after.

I suspect most of these routes are not really fixed, different drivers 
could cover the roads in a different order if they wanted to.

Comparing it to bus routes, you only map where the bus is actually 
carrying or picking up passengers, not where it is driving empty to and 
from the depot.
