Most of the time, riding a bike brings beauty, independence, joy, and healthy living. Rarely, bicycling can turn into disappointment or worse, tragedy. People who ride bicycles are in the midst of traffic which is massively bigger and heavier than the cyclists and their equipment. Trucks, cars, SUVs – they are sometimes operated by drivers who have little concern for us. We cyclists are largely unprotected, except for our helmets and the thinnest layer of clothing, and with hope that motorists will operate their vehicles safely with us in mind.
