I guess everyone has their style. And thats cool but is also inviting trouble. I rigged a small strobe on top of my headlight that activates with a momentary button on the handlebars. It is a very bright strobe and instantly gets the attention of anyone about to make a left turn.
The only time I ever go without helmet is at a bike rally. That is riding no more than 15 mph in a thick mass of bikes.
At the track...
