What makes Kansas different
That is a genuinely different decision model. In a banded point state a driver weighs how fast they were going; in Kansas the weighing is about position in a sequence, and a modest citation arriving as a third conviction is a far worse event than a fast one arriving as a first.
The fines themselves are low, so a Kansas driver reasoning about a citation in isolation will usually conclude it is a small matter — and for a first conviction that is right. The arithmetic changes entirely once there is something already on the record inside the window.
