There are races that look, in prospect, like processions and become, in practice, something else entirely. The 2019 German Grand Prix at Hockenheim was always going to be chaotic — the combination of a track that suits overtaking, a mixed weather forecast and a championship that was tightly contested guaranteed that — but nobody could have predicted the specific shape that chaos would take, or that it would leave Sebastian Vettel standing on the top step of the podium having started from the bottom of the grid.
Vettel had crashed in qualifying, his Ferrari finding a wall at the stadium section and damaging the car beyond repair for a timed run. He would start last. The gap between last place on the grid at Hockenheim and winning the race seemed, in the grid order before the lights went out, impossibly large.
The race started dry and became something else. Rain arrived in the middle portion, catching drivers on the wrong tyres, producing aquaplaning cars and gravel trap visitors in quick succession. Safety cars appeared and disappeared. Lewis Hamilton, who had been running at the front and seemed well-positioned for a dominant win, made a mistake under the changed conditions and drove into a barrier, retiring from a race he had been controlling. Valtteri Bottas, too, had difficulties. The front of the field rotated.
Vettel, whose race had been surgical — picking off cars at each opportunity, staying out of trouble while others found it, timing his tyre stops with Ferrari's strategy team against the changing conditions — emerged at the front. Daniil Kvyat, the Russian driver whose career had been through considerable turbulence, was behind him in the Toro Rosso — a result that nobody in the paddock had thought to consider when the afternoon began. Vettel won. He got out of the car and was still shaking his head at what had happened.
