I assume you are referring to Lewis’s misdemeanour yesterday when he spun off and rejoined forcing Paul Di Resta to run wide.
Although Lewis admitted being perhaps a little careless in his efforts to rejoin the race (and has apologised to Di Resta) even Di Resta accepts that the danger was minimal, he saw Hamilton in good time and that there was little chance of a collision. In my view the drive through penalty that Hamilton received was a little on the harsh side, but just about reasonable to comply with the rules. You have to remember that F1 is motor racing, jack. The drivers are there to win, and whilst they should not attempt to do so at any cost, they often take risks which you would not expect to see taken on the High Street on a busy Saturday afternoon. It is all very well sitting in your armchair with the benefit of ten super-slow-mo replays taken from every angle to make your analysis, but drivers do not have such luxuries and have to react immediately.
Far more serious yesterday, and a much greater hazard in my view was the action of the track recovery team (and to a certain extent the race director) in allowing Nick Heidfeld’s burnt out car to be towed backwards up the pit lane just where the cars leaving the pits get up to speed. Vettel almost came to grief as a result of this stupidity and the authorities have a lot to answer for.
