It's not all that uncommon for the person towing the wrecks to end up damaging themselves, the road or other vehicles by being just idiots with no ability to predict obvious outcomes.At the scene of a 911 accident, he decided to put the car in neutral so he could tow it without using wheel dollies. This was against common sense (you have no idea if the wreck damaged the drive train in a way that entire wheels could fall off just by rolling) and company policy - (you use dollies on all drive wheels unless you have, personally, removed the driveshaft)
He didn't even get that far.
The car rolled away
And struck the police car that had responded to the accident
He'd tried to stop it from doing so by stepping in between the wrecked car and police car at the last second and stopping the rolling car with his hands.
I had one where the genius sent to recover a car on it's side decided that rather than use the truck's equipment he'd simply rock it onto it's wheels. I was busy doing paperwork and next I hear is a big crashing sound. Look over and he'd managed to rock it just far enough that when it came back he couldn't stop it so ended up under it which added a whole load of extra work to the incident.
Another time they decided it didn't look too bad so they would drive it onto the truck (despite the offside front being almost entirely folded under the car in the crash). He started it up and drove for about 10 foot before both front wheels came off and put huge gouges in the road surface.
Finally I had one where they'd crashed during a pursuit and I had to quickly put the car out with my fire extinguisher due to it starting to catch alight from the heavy driving and crash. While I'm dealing with all the traffic, people who'd tried to get away etc the recovery guy starts up the car to drive it to the truck. Cue a lot of smoke and flames. I completely empties my extinguisher the first time so we could just watch it burn.
We keep cancelling towing company contracts for dumb shit their employees pull but the new company is always just as exceptional. How people stay alive in that line of work is a mystery.
