To the bicyclist that I almost killed on my way home this afternoon:

1. You should study your hand signals again.  Your left hand pointing down toward the ground with the palm to the rear indicates that you are braking.  It does not indicate that you are about to make a left turn from the right hand lane.  It still doesn’t indicate a left turn when you do it again emphatically with a rude gesture after I slam on my brakes and squeal my tires to keep from killing you and then honk my horn in exasperation.
2. Actually, making a left turn from the right lane is illegal under all circumstances, no matter what you are driving.  And it is particularly ill advised when you do it suddenly in front of a car going 30 mph when you are on a bicycle moving at about 10 mph.  I occasionally ride my bike to work — not as often as I should — so I’m not impervious to to the concerns of bicyclists on the roadways.  That’s why I gave you an entire, car-sized lane all to yourself.
3. You should consider wearing a helmet.  Because while you are unlikely to fare well going mano-a-mano with my Honda Civic, the next vehicle you tango with is likely to have higher mass and be considerably less nimble.

Thanks for reading.  Happy cycling.
