Speed traps are the only way you can accurately prove the speed of a car and is the reason why they are used by Guiness to validate a speed attemp . Like I said Cen car in that video does not look like it is going 70 mph and since Cen has not placed in any world speed attemps or even participated in any I doubt it can reach the speeds it claims on the box. So lets just agree to disagree until this Cen car gets released and tested. I will be getting one but it won't be stock for long I will be replacing the kit motor with a modified big block and replacing the radio and tires to see what it can do .
