Answer:
People who speed are rarely ticketed, so they continue to do so.
Explanation:
Circular reasoning is a logical fallacy. It happens when the reasoner begins with what they are trying to end with.
In this example, you can see how that happens. You can phrase it in many ways and the premise of the argument will always be also its conclusion:
people who speed are rarely ticketed, so they continue to do so
People speed because they are rarely ticketed
people are rarely ticketed, so they speed
people who speed only do that because they are rarely ticketed
