Michael Schumacher said he turned his own engine off at the beginning of the Hungarian Grand Prix in a misunderstanding over the delayed start.
The Hungaroring race start was delayed for reasons not yet clear, with the yellow lights flashing as cars formed up on the grid. The usual procedure is for cars to continue running and immediately do another formation lap, but Schumacher shut his Mercedes down and consequently had to start from the pitlane.
"We had the yellow lights and pretty high engine temperatures, and I decided to switch off the engine as we were waiting so long," he admitted.
The German's race then got worse still, with a puncture, a pitlane speeding penalty and ultimately a late retirement from 18th place.
"We had a puncture – I don't know how and what happened. There was obviously no contact, I was alone and by myself," said Schumacher. "Then we even had a drive-through because maybe the pitlane limiter or something didn't work properly during the puncture phase.
"That was the race decided. It was just trying to hang out and see if maybe something unusual would happen that we could take benefit from. In the end, because we'd had these engine temperatures and we had some telemetry issues, we decided to stop the car."
