说明

If you are driving East on SE 16th, wishing to turn left onto 148th Ave SE, the lights do not pick up the fact that your car is there.
Usually, those magnetic sensors (usually circular) under the road sense that your car has arrived, in order to turn the perpendicular street's lights red, and a few moments later, your light goes green and you can turn.
Not so at this intersection.
I've sat ther for 5 minutes before taking a free right (instead of my desired left onto 148th to head north) and taken another route to get where I was going.
