Felipe Massa has called on Sochi organisers to up the reaction time of their marshals after it took "very, very long" for help to reach Carlos Sainz.
The Toro Rosso driver is ok having suffered a horrific crash in Saturday's final practice for the Russian GP.
Sainz lost control of his STR10 under braking into Turn 13 and hit the outside wall before coming to a halt with his car buried under the barriers at the end of the run-off area.
Marshals and medics spent time extricate the Spaniard who was airlifted to hospital where he underwent tests.
Sainz is thankfully ok.
Massa, however, reckons Formula 1 needs to improve its reaction time as he reckons it took "very long" for marshals to reach the driver.
"The time it took is massive," he told Autosport.
"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."
He was also unhappy with the lack of information regarding Sainz's condition win the immediate aftermath of the crash.
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."
