It was the moment that defined the Tuscan Grand Prix. Four cars were taken out on the spot, the race was suspended for over 20 minutes as a result of it and when it restarted, Lewis Hamilton took the lead back from Valtteri Bottas, which he held until the chequered flag.
A stewards' inquiry followed, resulting in 12 drivers being issued with warnings but no single driver taking the full blame for the accident or being penalised with anything more than a slap on the wrist. So was it simply a racing incident or was there more that could have been done to avoid the carnage at the start of lap seven of the Tuscan Grand Prix?
