I don't remember any speed cameras. I live in NoCal but visit LA. I have seen a lot of red light cameras. But for the first two years I was not a permanent resident so kept my car licensed in FL. (Also no front tag!)
In CA the sex of the driver has to match that of the registered owner or they will not send out the ticket so I drive my wife's car when we are out.
BTW, she did get her photo taken a couple of years ago while "clearing the intersection" during a left turn light that went to red. Even if she "ran the red" it is rediculous that she gets the same fine and points as someone that blows through at 80.
They are considering intersection cameras here in Montgomery, AL (we have a SERIOUS problem with people running red lights). This is one of the main reasons I don't want them. They don't distinguish between a true run and "clearing the intersection" as you call it. If you are making a left turn, you have to get out in the intersection. Then, you are at the mercy of oncoming traffic. If they don't stop, you get your picture taken IN the intersection and get a ticket in the mail.
The best way of solving this problem is to not sit in the intersection, but instead wait in the turning lane until it's your turn to go.
