Am I an Overkill?

Maybe. Motorists may be too busy working out the red laser lines, and the rest of it, to watch the road. If a car driver is like some cyclists I know, who steer towards what they look at, you might inadvertently become the target.

Jokes aside, the main idea is to be noticed long before the driver cannot react in time to avoid you. Though these days with so many drivers texting, eating, and playing with the radio, its seems impossible not to be hit. IMHO a cyclist needs to be noticed and that is all. If I became a distraction I do not think I am helping the driver to avoid me, or others riding with me.

But please do whatever you need to do to feel safe. However, if you still feel apprehensive with all those visuals, then your confidence in riding, taking command of your space and applying the traffic rules in a positive and timely manner, will be hampered...as europa pointed out.
