Bicyclists want to share the road with cars, trucks, and motorcycles. That’s great, especially if you’re concerned about fitness and/or the environment. What isn’t great is when they think they’re somehow above the rules of the road. Things like not using hand signals to indicate they’re turning, sudden lane changes, and other erratic behavior makes it more dangerous for everyone -- but they’re the ones who will end up in the hospital if an accident happens, and it’s your insurance that will go up.
