A former Formula One team owner Eddie Jordan has described Sebastian Vettel's swerve into title rival Lewis Hamilton at the Azerbaijan Grand Prix as an "instant red card" offence in football.
Vettel was given a 10-second stop-and-go penalty for crashing his car into Hamilton's Mercedes on Sunday.
"It's the equivalent of a massive headbutt in soccer," Jordan said.
Vettel, who is a four time world champion, was given three licence penalty points for his actions, taking him to nine.
If he receives another three at the next race in Austria on 7-9 July, it would trigger an automatic ban for the British Grand Prix a week later.
"With the penalty points he received after the race, the stewards clearly had footage that the driver turned into Hamilton," Jordan told BBC Radio 5 live.
"This is never acceptable, whatever happened prior to that. You can never take the law into your own hands, certainly not in sport.
"So he got a 10-second penalty but it was a stop-and-go, which we say is equivalent to a 40-second penalty."
Jordan says he is unsure whether the 29-year-old German Ferrari driver should face more sanctions although he feels the spat would be "good for the sport" in marketing terms, but he expects the pair to quickly make up.
"There's actually quite a bit of love between those two, or respect, they appreciate each other, so I don't think there was any malice between them, what happened happened and they will move onto the next race," he said.
Following the crash, Vettel claimed he responded as he did because Hamilton had 'brake-tested' him - deliberately slowed down to cause him trouble.
Stewards examined data from Hamilton's car and concluded he had done nothing wrong - he had merely not accelerated out of the corner as he prepared the restart, as is his right.
Hamilton ended the race - won by Daniel Ricciardo - in fifth, a place behind Vettel, and is 14 points behind the German after eight of 20 races.
