Actually a good point....whats the difference between a ditch, snow drifts, or stuck cars? They are all objects that prevent movement. From the tow company POV, perhaps they got a call that said we have x number of cars stuck, the tow company said
(x) x $80 is worth my time to head out in this crap.
The unfair part is that they had no other options. I have AAA and pay $80 per year so I don't have to pay out of pocket for this. So I can see both sides.
Simply with cars you cant solve the problem yourself without assulting someone else. With a snow drift you could shovel it away get a friend with a plow to help or just drive thru it. The ditch could be solved if you owned a winch or had a friend with a winch or tractor. If you moved a car that person would most like consider you stealing it or try and stop you from pushing them out of the way and possibly into a ditch. What would you do is someone started pushing your car off the road?
