General Discussion

will save far more lives than helmets on either riders or drivers.

I see bicyclists and motorcyclists doing unsafe things and making unsafe assumptions frequently. By the same token, I see drivers not paying attention to their driving frequently, as well.

Helmets have some value, but not as high a value as riding and driving safely and attentively.

When I got my first motorcycle, a very wise person told me that I should treat all enclosed vehicles as if they were planning to run into me. It was excellent advice, and it saved my sorry ass many times while riding. The same thing applies to bicyclists. Drivers will turn right in front of you. They will open their car door without looking to see if a bicycle is approaching, and they will drive on on an intersecting street or road if there is no stop sign there. Going through a stop sign on a bicycle is a very dangerous thing to do, and yet I see bicyclists doing it all the time in my residential neighborhood, and have observed a number of close calls. As a car driver, I always assume that the bicycle and other traffic crossing my direction of travel will ignore stop signs, so exercise caution, since I've seen it happen so many time.

Assume the worst case when you're on the road, whatever means of transport you use, and you'll probably avoid 80% of accidents.
