Valtteri Bottas has revealed that he accidentally reacted to lights on his Mercedes' steering wheel at the start of the Hungarian Grand Prix, resulting in a slow start from second on the grid.
The error saw him drop to sixth by the first corner and the recovery drive that followed meant he finished in third behind Max Verstappen on a weekend when his car had the pace to finish an easy second behind teammate Lewis Hamilton.
Bottas was not penalised for what appeared to be a jump start because his movement was within the tolerance allowed by the FIA, but he still lost crucial positions early in the race as his car kicked into anti-stall a result of the error.
