As far as the spray goes, my understanding is, a $3 can of hair spray from the local drug store will do the dame thing. The only issue, you have to re-apply about every month or so.

Also, just to be clear.. I don't think any of us intentionally run red lights. But, sometimes we slip a little through a yellow.
Now lets look at Calif. law for a second, the law states that if your car has entered the intersection anytime when the light was yellow, you have not run a red light. But, these photo booths still issue a ticket for it for a late yellow pass through. Again though, no one fights it..

These machines have one purpose and one purpose only. To generate revenue. They are not even installed at the "dangerous" intersecitons. They place them in areas where they expect to do the most business, like on a down hill traffic light where people might not brake in time..

Also, FYI.. these machines are not operated by the city. They are operated by private companies contracted by the city. And, the company gets a percentage of each fine imposed on the driver. So these companies who set up, maintain and issue tickets do not select locations based on "past traffic accidents" or "problem intersections." They place them in specific areas where they have calculated to generate the most revenue with no regards in improving road safety. The more tickets they issue, the more money the company makes...
