Motion sensor makes new Muni gates easy to exploit

San Francisco's Muni says it's stepping up enforcement to catch people trying to exploit a feature in new fare gates being installed in Muni metro stations.

The gates use a motion sensor to open automatically when someone exits. Some riders have discovered the sensors can be activated by reaching over the gate and waving a hand to enter without paying.

Muni says there's no short-term fix for the problem.

The new $30 million system, which is part of the transition to the Clipper card program, is expected to be installed at all Muni stations by next month.
