> many school zones do not have a flashing light and instead have a timetable printed on the sign. This requires you to know at an instant: The current time (which depending on what you drive may not be accessible), If school is actively in session (If you don't have kids or are in a different area you may not know this)

Doesn't that imply that there should just be flashing lights adding to existing school zones, not that we eliminate them?

How does it generate revenue? I don't generally spend money when I'm slowing down for a school zone.
