We've been noticing more stringent enforcement of traffic laws at Shanghai's major intersections over the past few months. At one of Shanghai's busiest intersections, we recently noticed an interesting voting booth / suggestion box created by LEGO.

The “Satisfaction Post” (满意柱) allows citizens to vote on whether they are satisfied or not with the local police's ability to control traffic.  Placing a red ring on a small plastic pillar means “satisfied,” while a blue ring means “unsatisfied.” Below the ringed voting system is a slit to submit any feedback.
