Some drivers simply don't see bicycles, or when they see them, they forget them immediately or think they are still where they were when last seen. They tend to remember "I have a car behind me", but "I have a bicycle behind me" somehow doesn't register - which means they may take a sharp right or pull over in front of a biker they just passed and completely forgot about.

Instead you often see bikers disregarding the vehicle's turn signals and continue riding straight ahead into the car's path without stopping. Bicyclists are required to behave as a vehicle would and not a pedestrian.

Isn't that so by default? We learned that by 5th grade. You're a "partaker in traffic" this way or other. Even a pedestrian is, now and then.
