That's something you'd better not get into the habit of doing on the streets of LA.
Yesterday I was crossing a major intersection with a green light, though the "Don't walk" sign was flashing at the crosswalk. As I approached the intersection I saw a red car approaching in the opposing left turn lane, and I said to myself, That SOB looks like he might not stop for me. I rang my bell to get his attention, and kept on going.
So did he. Even when he appeared to be looking right at me. Eventually I decided it was time to take evasive action, which I did, though he did come within five feet of me as he swung through the turn. It was close enough that a woman in a car waiting at the cross street screamed.
Then today I was in the harbor area of Long Beach, when I went through an intersection and turned to go left—making the supposedly-safer box turn. There was a road crew working on the street I had just crossed, which may have blocked sight lines somewhat. As I reached the far corner, the light turned green in the direction I wanted to go in. I waited a second—I was stopped anyway—and pedaled on.
Only to find a black car approaching on my left, running—albeit slowly—the red light. I was moving too slowly myself to dodge, but the driver was more on the ball than Red Car Guy, and he stopped.
It would have been at least a broken leg if he hadn't.
I think I need to refurbish my mistruster. Two in two days is three too many.
