How far apart are these two G's?
as i thought about it.. u can go as fast as the car that is in front of u.. for example of car A is moving at a rate of 60 mph and u are behind car B u can't be going 61 mph.. just any idea.. However car A might get a ticket as well
A lot of these are actually RENTED from a 3rd party company who sends you information regarding the ticket. They actually make $$ from each ticket. There is reasonable doubt that the photo cop tickets can be rigged to target every X number of drivers regardless of speed. Since the company stands to make a profit from this I would argue there is enough cause to throw the case out.
Also, the best way to determine your distance is to measure the center of the wheels. You can determine how far between based on wheel base and then appropriately scale the picture. Then measure distance between front and rear tires and multiply by scale. You will then have the overall distance traveled between #1 and #2.

OP, go back to the site and measure everything. I hate these stupid cameras. Let me know if you need help. Im in the MD/DC area.

It just hit me on the way home....
I thought that it was a federal law that all speed detection devices (i.e. radar & laser) must be re-calibrated once a year. You might check into that, contest the ticket and tell them you would like to see the calibration records for the unit that clocked your car at the said speeds.

BTW, I asked for the calibration records, etc and have already received them..
Everything checks out......

I am actually trying to prove that their system was wrong, not that they are getting money from these tickets. The State Highway Adm in MD actually has a contract in place that pays the company around $1700 per day for each vehicle with speed camera operated. Therefore, this system doesn't pay them per ticket. (I have a copy of the official contract - FOI Act is great).
using photshop, I measured (in inches) the wheel base.
1st car = 1.823"
2nd car = 2.334"
true wheelbase is 120"
What else do I need?

Your estimate of around 12ft distance, can't be correct, as the car itself is 15.5 feet, and one can see that it moved at least one car length, plus there may be around 2' of gap between the two.
My best guess/estimate would be that the car moved a total of 17-18 feet.

Isn't there a way in PS to take measurements in 3D? "Vanishing Point" or something?
You guys need to pay attention to perspective too. As the car travels forward, the angle you view it at also changes slightly. As a result the distances used as references also change as well slightly.
Without knowing the angle that both cars are viewed at you really can't devise a clever way to figure this out
