Felipe Massa wants faster reaction and information after F1 crashes

Sainz lost control under braking for Turn 13, slamming into the outside concrete wall before heading straight on into the barrier at the edge of the run-off area.

The marshals then had to tend to Sainz, whose car was buried underneath the Tecpro barrier.

It was also some time before any replays of how the incident had unfolded were shown, with the television director choosing to delay doing so until it was clear the Spaniard was OK.

"The time it took is massive," said Massa, who qualified 15th after failing to get a lap together in Q2.

"If we're going to race in new tracks where they don't have so much experience in racing, they need to think about bringing marshals from other races so they know what to do in a quick way.

"It took very, very long."

With regards the television coverage, Massa said it would be useful if the director could put up a message onscreen to reassure viewers about Sainz's condition.

Massa said: "The only thing I was really scared about was that television didn't show anything.

"We didn't know what happened. They were just showing the face of the people, waiting to have an answer. Nobody knew.

"I kept thinking about the family - they have no idea what is going on. This is something I do not accept.

"They need to have a message. If he is OK, the television [director] needs to know straight away and put a message out that he is OK."
