Impounded Cars and Totaled Cars should need to be taken to a graveyard/tow yard. Why? Not every car is fixable after a crash. What is the joy in pressing a key or two, waiting, then a car disappearing? To really keep that immersion, crashes should need to be towed or loaded onto a flatbed in order to clean a scene. Impounded cars should be towed instead of just disappearing. Another idea: Uncleaned crashes or abandoned cars will disappear after a long set time (waste management) but the city will be fined for the "cost". This way it keeps the economy alive and adds use to public funds. Maybe even the car owner would be fined as well. It will also create a necessity for the jobs to be filled in order to cut costs. Supply and Demand.
