Bug?

Vettel says that's ok.

Where is Charlie? I want his answer.

I've gotten this before

At 11s you rolled a bit forward. There are few centimeters tolerance for rolling before green light, so nothing happend. But then maybe later the car moved another 1mm (possible by steering?) that is invisible on video and that put you over the limit.

Or the penality for the initial movement was somehow delayed/lag.
