More importantly: parking illegally often endangers or harms other people (e.g. by blocking fire hydrants that might be needed in an emergency, or by impeding the flow of traffic).
Parking illegally in a specific spot could result in the death of 8 people? then the fine should be 8 * value of life. the value of life is ~ $9M in the US, so the fine should be 72 million dollars.
Likewise, if the car is impeding traffic, tow it out of there. The fine does nothing to fix the problem.
