What is it about the colour Red?

And yellow or orange? Do these colours send electric impulses through the eyes of the observer, usually in a motor vehicle, causing them to press their accelerators down even harder? Do they make individuals rage with fury at the thought of being stopped? Hence the urge to attack and move forward at speed, rather than stop? Is there any way to reverse this automatic response in some?

A challenge: today stop at every red traffic light

So a challenge: today stop at every red traffic light and red stop sign.  Stop. Breathe. Look around. Not at your phone. Look around. Be surprised. You may even get to your destination on time.
