So I’m for the time being watching the 1978 season after I stumbled on this. On the entire in that age, the fitting technique used to be 0 pit stops, that means that pit stops had been unplanned nearly every time. But here, Ferrari had been combating their Michelin soft tyres, so that they called their drivers for a tyre change ahead, in the equal lap. They in fact did a somewhat high-quality job focused on the pit stops from that age, although they misplaced a tiny bit of time on Villeneuve. Anyway, they’d stop up no longer scoring at all in that rush, however this is in a position to well be the first double pit stop ever in F1 (or as a minimal, the first one ever recorded).
