I was riding on a 45mph 3 lane road approaching an intersection where our direction was green. The car in front of me starts slowing down, so I match. Our light was green, cars are flying by at 45+ mph, and I can see over the car and there is nothing in front (no traffic, accidents, etc). So I assume they are just adjusting their speed. The last thing I expect is for them to stop, but of course that is what they plan to do.

I didn't realize this right away because I had glanced in my mirror to try to get around him. Once I saw that I had to STOP, it was almost too late. I gave a little too much rear so it locked and slid out of alignment. I barely stopped in time (and upright), and then the car behind almost rear ended me. Turns out the guy thought he was in the left turn lane, where there was a red arrow. He turned his blinker on and waited patiently at his perfectly green light.

Moral: if someone is slowing down in front of you, don't ever glance away. Even if you are 99.9% sure they are just adjusting their speed, they might be making a complete stop.
