I just did a 4 month internship in San Diego, and I drove to work.
I'm used to Ontario traffic lights being a certain length of yellow. And then, there's usually a pause between the two sets of traffic lights (i.e. there's a small amount of time where all lights are red).
Imagine my surprise in Southern California that this was not the case at all. The yellows were MUCH longer, throwing me off completely. I'd slow to a stop in anticipation of the red, only to see it stay yellow for a while.
So a few times, I "dared" to just go through the yellow. I thought they were questionable, but to my surprise, at least one or two drivers would follow behind me. If it was questionable for me, how are they pulling it off?
There's no pause between reds either. The whole situation just seemed so unsafe. And then I saw a piece on the local news about red lights, and how the city is earning lots of money from it.
If you want an example of who's got the traffic light timing perfect, look to Ontario.
