BD example: feedback sign

If you have ever been to Amsterdam, you will know that cyclists violate the rules, notoriously. This sign provides feedback to cyclists that violating the sign will result in a 55 euro fine. This links to the fourth principle of behaviour design: interactivity. Unfortunately, if there is no actual follow through, the effect wil eventually wear off. It would be even better if the sign included a detour/ alternative route, and allows cyclists to take initiative and have more sense of control.
