You're right, some motorcyclist is going to pull out and get hit by oncoming traffic.
REPEAL THIS LAW
Oh, and ban all those highway crossing where only the side streets have stop signs.
4 WAY STOPS EVERYWHERE.
Isn't that effectively what this does, makes 4 way traffic controlled stops into "Warning, cross traffic does not stop" crossings?
Motorcylists don't like playing the Reality version of Frogger any more than pedestrians or little green frogs. Are some morons going to blow through lights without stopping? Yes. Do morons do that whether riding on top of a Honda or seated in their Civic now? Yes. This simply brings reasonability back to traffic flow regulation. Signs and lights are there to reduce collisions. So making adjustments to allow the flow to continue without significant safety decrease to others is only reasonable.
For the record, sold my bike years ago. Found it boring (I like the radio) and more of a hassle than it was worth as transportation. Now I just have a small car instead and still run into the traffic light problem during periods of light traffic. Such as at night, 4am stoplights really hate me. Usually if I rock back and forth I can trip the sensor, but after awhile I give up on it and go if it's a small downtown intersection, or make a wide right on red to stay somewhat legal on the highway crossing.
