There were amazing scenes at San Marino Moto2 on Sunday when Romano Fenati tried to grab another driver's brake while running at 140 mph.
Fenati can be seen in an extraordinary video mounted along with his Italian compatriot Stefano Manzi, before extending his hand and trying to tighten the brake of the right handlebar of his rival.
The British MotoGP rider, Cal Crutchlow, has requested that Fenati be suspended for life after the shocking incident, which fortunately did not result in a serious accident.

Fenati was then disqualified from the series race after his dangerous act on Sunday
Manzi's Suter bicycle shook briefly after Fenati's intervention, but managed to regain control and continue the race.
"I should never compete on a motorcycle again," said Crutchlow, who finished third in the MotoGP main race later that day.
– He should have gone back to the garage and his team should have kicked him straight in the back.
"You can not do this to another motorcycle rider, we're risking our lives enough."
Fenati, riding for Marinelli Rivacold Snipers, has been benignly banned for two races after being disqualified from the race after the incident, which occurred on lap 23.
The pair had contacted each other earlier in the race when Manzi tried to overtake Fenati, and both riders ran out of the track before re-entering and continuing the race, but losing positions to their rivals.
The incident seems to have infuriated Fenati, which led to his reckless reaction.
"We had a contact two turns before, but nothing to justify such a reaction, his gesture speaks for itself," Manzi said.

Fenati has a reputation as a hothead after a series of incidents during his career.
In a BT Sport video, he can be seen kicking an opponent's bicycle while competing in another amazing and highly dangerous attack.
He also has a reputation for arguing heatedly with other riders, and can be seen flipping a rival's bike, raising his middle finger and being physically aggressive on the grid.
Former MotoGP rider Colin Edwards, commenting on BT Sport, said Fenati had "put someone's life in danger" and added: "This is amazing. Are you kidding me?"
The four-time MotoGP world champion, Marc Márquez, asked Fenati to be suspended.
"They need to put a punishment that the other guys will never do … that if you do this, you will not compete," he said.
The 32-year-old Italian Andrea Dovizioso won the San Marino Grand Prix at the weekend
Marc Márquez finished second to increase his advantage in the MotoGP championship to 67 points
The Italian Andrea Dovizioso won the San Marino Grand Prix, while the world champion Márquez finished second and increased his advantage in the MotoGP championship to 67 points.
The local favorite, Valentino Rossi, managed just a distant seventh for Yamaha and lost the overall second place to Dovizioso, who now has 154 points and Spain's Marquez, 221, with six races left. Rossi is 151.
Jorge Lorenzo de Ducati, who had started on the pole position at the Marco Simoncelli circuit on the Adriatic coast of Italy, crashed on the penultimate lap as he was heading for a Ducati brace.
That raised Crutchlow, whose home race at Silverstone last month was canceled due to heavy rain and drainage problems, to third place as the leading non-manufacturing finisher in a LCR-Honda.
