This is what Whitmarsh said first
http://www.autosport.com/news/report.php/id/106349"For about 120 milliseconds, he had a green light, so with lightning-speed reaction - just as he's paid to do - he pulled away," Whitmarsh said.
"Those lights are controlled by a whole number of circumstances, like micro-switches and buttons that are around the car and a button was pressed and then released for about 120 milliseconds.
"These people are trying to do sub-two-second stops. There's a lot going on in that time and a lot of pressure on people. Human error resulted in a green light.
"It's one of those occasions when you wish your driver wasn't so quick off the mark..."
When you combine that with Brundle pointing out that Button was jumping the gun a little at pitstops at the last race things are no longer as straightforward
A button was pressed and released for about 120 milliseconds? Surely not by the guy who knew he hadnt completed his task. Is nt the idea of the electronic system that every participant reports directly to the control unit that he is done, so avoiding a human relying on signals?
So who pushed the button for the guy who knew he hadnt completed his task? who pushed and released it?
