There are no true victimless crimes.
Even crimes against society are crimes.

The child molester or rapist relies on anonymity to be able to commit his deeds. When forwarned, society watches these people to prevent recurrence.
Their crimes are not committed in public.
Speeding, on the other hand, is a very public offense - anyone else on or near the road is able to see it.
