Jenson Button does not believe Lewis Hamilton would remain in Formula 1 if he found himself dropping from the front of the grid, as Button did in the latter stages of his career.
Hamilton stands on the precipice of a sixth world title and can wrap up his latest championship triumph in Mexico this weekend if he outscores Mercedes team-mate Valtteri Bottas by 14 points.
After securing his world championship in 2009 with Brawn, Button switched to McLaren, where he partnered Hamilton for three years, but the team's issues with Honda led to Button enduring a frustrating end to his F1 career.
By contrast, Hamilton is beginning to take several all-time records, including Michael Schumacher's for wins and world titles, which Button says will sustain his former team-mate's desire.
"He's always going to try to beat that record," Button told the Evening Standard.
