“The stewards reviewed positioning/marshalling system data, video and determined that the video appeared to show that Car 4 moved before the start signal was given,” their report began.
“However, the FIA approved and supplied transponder fitted on the car did not indicate a jump start.
“Article 48.1 a) of the Formula One Sporting Regulations states clearly that the judgment of whether or not there was a jump start is to be made in accordance with the transponder, which did not show a jump start. In the circumstances, we took no further action
If it’s faulty, you don’t know that it is. Which means you can’t reliably use that.
And that is what i am trying to highlight through my question. The rule is enforced completely based on the transponder but if its malfunctioning then drivers will not be penalized as the the transponder has not picked up their jump start.
