Furious Grosjean says Monza qualifying should never have started

Grosjean shunted on the start/finish straight at Monza in Q1, just after completing a time that was third quickest.

His car appeared to aquaplane twice, before he speared left into the guardrail, then bounced back across the track to hit the wall on the other side too.

"I'm going to try to be calm, and not say anything I may regret, but I think we shouldn't have launched qualy," Grosjean told NBC.

"From the out-lap onwards, I complained a lot saying that it was too dangerous, we couldn't see where we were. I don't think I was the only one.

"Clearly, crashing in a straight line shows that the car cannot take it. There was too much water. I'm disappointed that we started qualy in those conditions, what can you do?

"You cannot back off, if there's someone behind you he's straight in the back of you. You don't know what's in front. We should have waited."

When asked if the aquaplaning was worse on the 2017 tyres, the GPDA director replied: "It felt alright on the first lap, but the rain came stronger I believe for the second push lap.

"We know we have more aquaplaning on these tyres, it was fine most of the track, just the straight line, brand new tarmac, not clearing the water. It was just too dangerous.

"I think when the FIA brings the safety, to slow down a lot under double waved flags, the Halo is coming in… But launching a qualy which shouldn't have taken place, or at least after the out lap didn't seem that it was possible to run, I believe that decision should've been made a bit more differently."

Asked about the severity of crash by Sky Sports F1, Grosjean replied: "The impact wasn't strong, I was lucky, I hit the barriers and the move was still going towards the track, so I was happy with that, and lucky with that.

"But spinning on a straight is not what you should see in Formula 1. We shouldn't have gone out at all, I'm pretty straightforward on that."
