Following Hamilton clinching a sixth World Drivers' Championship title in , ex-Formula One driver and pundit Johnny Herbert acclaimed Hamilton as the greatest driver ever, a sentiment echoed by his Mercedes team-boss Toto Wolff, who described him as "maybe the best driver that has ever existed", while Formula One staff writer, Greg Stuart, described Hamilton as "arguably the most complete Formula driver ever". After Hamilton won his seventh title in 2020, John Watson stated that Hamilton "is, by a million miles, the greatest driver of his generation and you can argue he will go on to be the greatest Formula One driver of all time", and highlighted his fearlessness as being key to his success, as evidenced by his performance against double world champion team-mate Alonso in his rookie season and his decision to leave McLaren for Mercedes.
