Lewis Hamilton says being squeezed by Formula 1 rival Sebastian Vettel at the start of the 2019 Mexican Grand Prix risked a "big collision" on a "hair-raising" first lap.
Hamilton was squeezed by Vettel on the run down to Turn 1 as they chased polesitter Charles Leclerc at the start of the race, a move he branded "dangerous", before he briefly lost the rear of his car on the kerb exiting the first corner as Verstappen tried to pass on the inside.
That moment almost caused Hamilton to hit Vettel's Ferrari and although he ended up spearing right and forcing himself and Verstappen onto the grass, he avoided contact and went on to recover from fifth place to win the race.
When Hamilton said in the post-race press conference that Vettel had tried his best to block him at the start, Vettel said he did not see him, then laughed: "But if I'd seen you, yes I would have tried!"
Talking through the first lap in more detail, Hamilton said: "I actually got a really good start and was pulling up to Charles - and Seb's coming across, coming across, coming across and I'm thinking 'I'm on the white line, I don't have any further to go...'.
"And he just keeps coming and I had to avoid crashing with him on the grass, and avoid his wheels as well otherwise it could have caused a big collision for him.
"Then I was surrounded by a bunch of cars, braked into Turn 1 and all of a sudden Max is alongside.
"If you've seen races before I always leave Max a lot of space. It's the smartest thing you can do. But there wasn't a lot of space to give.
"Then I nearly took [Vettel] out. My back end came out and went straight on the grass - it was hair-raising."
Hamilton joked that he got "torpedoed" by Verstappen's move down the inside, with the Red Bull driver then squeezing Hamilton wide and triggering Hamilton's lurid moment.
He added: "The first time! I thought at some stage I'd get torpedoed by Max!"
Mercedes team boss Toto Wolff hailed Hamilton for avoiding "race-ending situations" on the first lap.
Wolff said: "This is clearly something is a combination of talent and learning and experience.
"He's really great. On a few occasions he took himself out of what would have been a race-ending situation.
"At Montreal with Sebastian, where he avoided contact miraculously [after Vettel went off and rejoined in a manner that squeezed Hamilton against the wall].
"Then contact here with Seb on the straight and then just a few seconds later being side-by-side with Max through Turns 2 and 3.
"He seems to have this great ability of putting this car in the right place."
Wolff described Vettel's move left towards Hamilton on the straight at the start as a "very hard move", but accepted the Ferrari driver said he did not know Hamilton was there.
"It was front right and left rear, and these things can end up bad on the straight at [many] kilometres an hour," said Wolff.
