Unfortunately, this isn't always the case therefore we create more laws to protect the innocent. I'm always surprised with the number of people who are angry with cyclists for no apparent reason other than they are on the same road as their automobile, how absurd. Motorists should be aware of cyclists for the simple fact that they can indeed kill us in one small swipe. Use some common sense, and please, most importantly, let us all enjoy our surroundings without being so hateful. Having experienced some close calls, I believe cyclists need to be protected from motorists.
Most bicyclists are considerate of their gas-guzzling cousins.
A few are clearly not. The most important law from my perspective is that everyone knows what portion of the roadway bicyclists will occupy. Signaling is always courteous and helpful, whether you are in a car or on a bike. This practice arguably puts careful drivers who observe the speed limit at risk for hitting bicyclists. A little common sense and consideration all around would go a long way toward easing tensions.
