Speed Tickets Challenged Based On Timestamped Photos

SEWilco writes "A businessman has challenged automated tickets of his vehicles by calculating the vehicle speed based upon the tickets, which include timestamps of two photos." Maybe more word problems should be on the police academy curriculum.

    also if you had read the article you would have also noticed that the pictures are taken roughly 50ft after the car passes the speed sensors

    according to google... 50 mph = 73.3333333 feet per second

    so that gives the vehicle about an additional .68 seconds to decelerate before the first picture is even taken.

    so assuming your calculations above are right that is roughly 15 mph of braking the car could do before the first photo is even taken....50mph-15mph=35 mph...which could put him at the speed limit before the first photo is taken.

    this was just some quick estimation, but i think the calculations work out.

    Hey, if they just remove the points I might have a bit less of an issue with it. I mean if you can just drive however you want as long as you have the money for the tickets.....

    In New Orleans, they did JUST THAT!!

    They put up what I thought were stoplight cameras...no problem I stop.

    I didn't know they were also speed cameras....and there is a lag time between getting popped, and you receiving your ticket in the mail...a fucking MONTH!!

    This was on my route to work..I got 7 of them...lucky it was ONLY 7.

    But on the back of each ticket...it says clearly that "this is not a moving violation and will not go on your record".

    This is NOTHING but revenue generation.

    The nice folks in Jefferson Parish, next to us..voted these damned things out...with they people in Orleans Parish would do the same.

    Just to add some points of comparison:

    Normal hard braking is about 0.4 Gs.
    Skilled hard braking is around 0.7 Gs.
    Around 1 G seems to be the limit for skilled braking with performance tires and a great road surface.
