Sykes is one of the rotating hosts of The Daily Show and she had a good segment about how some local communities use speeding tickets as a source of revenue, by adding all manner of other fees to the fine itself. They even put poor people in jail for inability to pay the fines, and then add on more costs to pay for their incarceration.
She says that these fines are hardly a deterrent for rich people and recommends the model of some countries like Finland where the penalty is proportional to a person’s income, and where a Nokia executive got hit with a $103,000 speeding ticket.
