Just start arresting them and the problem is solved.
Kind of like a parent that wonders why their children do not behave. No enforcement.
Put a camera on the styles and an arresting officer around the corner. Keep the cameras and have officers in place as needed.
Make the fines steep enough that they include a transit pass for them in the future.
“....Put a camera on the styles and an arresting officer around the corner....”
Right on!
