So I have noticed that the airport vehicles are not using the runways to tranvel to an incident. So they are taking a long time in some cases 3-4 mins to travel to a job as they are going the long way around via public roads.
I think airport vehicles should travel in straight lines (like aircraft) if they are within a short distance from the incident. If its a long way from the incident travel via roads as normal as this would indicate they are travelling to a nearby airport for assitance.
