I have commuted by bike for the last forty years, the vast majority of the time. Be as bright as possible. Today I rode with two headlamps - one flashing and mounted on the handlebars and a brighter one on my helmet. There is a blinking red on the rear of my helmet and another on my seat bag. I always wear a bright jersey or jacket - screaming yellow or luminous green.

I am fortunate. The streets are wide and the drivers are courteous - probably a good fraction of them are recreational cyclists.

I average an "incident" about once every five years. On one of these occasions, the drunk driver was led from the scene in handcuffs - the bike was totaled; I was not.
