Can we say waste of resources

On my way down Dawes Rd. this morning I was backed up a few cars due to a car that had nose dived into the shallow ditch by the road. They didn't go in very fast as the hood was not even dented. It was almost like they made to wide of a turn out of the gas station. Anyway, the tow truck had not arrived, any emergency vehicles had long gone and traffic was maybe 8 cars deap on this 2 lane road. So I ask you this:

Why would it take 7...count them...7 police cars to handle this ditch abuse? One poor rookie with the ill-fitting uniform was directing traffic while the rest of the officers were just grouped up chit chatting. No one was doing any paper work. No witnesses were being interviewed. No arrests were being made. Now I may not know all the details to this little fender bender, but is there not some kind of police work that can be done out there? I am in no way trying to bad mouth the police department. They do a job I would never consider, but I wish someone could explain to me what it is that a patrolman does during his 8 hour shift. I felt like i should pull over and ask them if there wasn't some work that needed to be done somewhere.
