Stop pretending that you're seeing these cyclists performing an Idaho stop during busy traffic. You know full well they're paying attention a whole hell of a lot more than you considering their life is on the line. You may not see us looking both ways, because it only takes about 15 degrees of head movement to allow our eyes to capture the full peripheral to check for oncoming traffic and it's a hell of a lot more convenient for the drivers behind us to have some distance between us.
The only reason this is a big deal is because humans are barely different from monkeys on an emotional level and can't rational handle the concept of there being a different legal context for a bike vs. a motor vehicle.
