The Ducati rider will start the next race at Assen from the rear of the grid, as a penalty for collecting Lorenzo at Turn 10.

It is Iannone's second grid penalty of the year, the previous a three-place drop at Austin after he clashed with team-mate Andrea Dovizioso on the final lap at Termas de Rio Hondo.

The rules around penalty points have been tweaked this year following a judicial review, but Lorenzo feels MotoGP needs to take a harder line on repeat offenders.

"For me at this moment with the rules of points, we are not in a good way," he said.

"[In 2003], [John] Hopkins made a mistake at Motegi and had one race off. I made two mistakes in 2005 [in 250cc] and had one race off.

"In soccer, if you make a hard tackle, it's a red card and a minimum of one match off.

"In this sport, we play with our life, I could have broken my hip and collarbone.

"If I'm an aggressive rider like I could be in the past, sometimes we are not conscious of the risk, you need a hard conversation.

"If you don't have a harsh penalty you don't learn, you don't change."

Lorenzo was due to speak to the FIM's MotoGP race director Mike Webb on Sunday evening, and indicated he would end his absence from the riders' safety commission at Assen later this month to discuss possible changes.

"I will not appeal [Iannone's penalty] because they will not change the decision, but I will speak with Mike Webb and I will try to speak to the safety commission about this," he said.

"Sometimes you just understand that something must be changed when it happens to you, so let's see if the other riders also have a similar opinion to me, and let's see if we can do together something.

"When I was 17 or 18 in 2005, if I didn't get the penalty I wouldn't change. And I would remain the same.

"I don't know if it's enough for Andrea to understand that he needs to change something a little bit to avoid these kinds of actions.

"He is making these kinds of mistakes and finally if you ride like that when you are fighting with other riders, if you don't change your way of riding, sooner or later something happens."
