There are at least a few problems with contracted areas, so it's not a perfect solution. It basically excludes little guys as they dont have the fleet necessary to cover the contract (and in my experience, many of the little guys are good). It also drives the cost of the pickup to the moon unless locked down by government oversight (in which case, the competition for the area isnt much more than an illusion). If company a says they will pay the government 500,000 a year for the contract, they may charge $500 to get you to the safe location. Company b says they will pay the government $1,000,000 a year, they will charge the motorist $1,000. Which contract do you think the government will take? If the government says "you can charge $100 per tow", companie find a way to squeeze more out of motorists as they are used to much higher vulture rates (technology charge, dolly charge, etc).
