After seeing billvp's link, I am really .

Looking up wikipedia about traffic lights, I find that the standards I used to know that were current in the mid 90's are totally bonkered??? Some programmers/jurisdictions allow one second for every ten mph (for yellows). This is crazy! How screwed up is this? So in these jurisdictions, you have to remember the speed limits on the roads you travel, to know if you can 'beat' the red? Crazy man! Not to mention, any judge or cop will tell you to not memorize speed limits because they can change at any time. I digress... Its no wonder people are running red lights. Look how many different jurisdictions are 'doing their own thing' with traffic control. And, what happens when you move, or travel to another state or go out of town on vacation to another jurisdiction, and you 'expect' a yellow in a 45mph zone to last 4.5 seconds..... Totally crazy... I have some digging to do in my old archives for the references I had to use when programming traffic controllers.....

It seems standardization has long gone by the wayside... Best advice I can give now, is when you see a yellow, slow to a stop. If you get corned by someone in the rear, he/she was 'following too closely' and its their ticket. I sure as hell will not run through a yellow unless I saw it turn yellow and can make it through the intersection WITHIN two seconds.

I surely do not look forward to having my XF get 'creamed'...
