I saw a clip on Techtv before it was G4 there was is like Blackbox device that can be plug into your car like year 96 and above. You can plug it to a computer and it shows you how fast your going, how many times you brake, accerlation, decerlation ,etc and they sell this device. What is it called and where can I find one? Is good to prove if you weren't speeding and you get a speeding ticket.
