In a shock move following recent criticisms, the governing body on Thursday revealed a further clarification.
The headline is that a driver like Nico Rosberg at Silverstone who is told about a problem must now pull into the pit-lane during a race to have it fixed.
Four time world champion Sebastian Vettel has angrily described the revised radio rules as “a joke” and ‘disappointing’ about track limits in Hungary.
The Ferrari ace, Vettel pulled no punches at all, blasting the “b——t” radio rules.
Asked what he thought of the FIA’s decision, Vettel said: “Complete bull****. I think all the radio issues we have is a joke.
“I looked at the race after and I thought as a spectator it was quite entertaining to hear a driver a little bit panicking on the radio and the team panicking at the same time.
“I think it was the human being in our sport, that is arguably very complicated and technical, so I think it’s the wrong way.
“There’s a lot of boring stuff on the radio that got banned, I don’t see the point. If you want to change it you should change the cars. You should be able to say what you want.”
Sensor will be used on Turns Four and 11 at the resurfaced Hungaroring in a bid to stop drivers exceeding track limits, and Vettel once again didn’t hold back.
” I think it’s the FIA to blame [as they build] circuits where it’s faster to run off the track than it is to run on the track,” he added.
“I went round the track this morning and it’s quite disappointing. I think quite a lot of money went into it and I guess this place had to pay to put certain type of kerbs in place. It doesn’t make much sense.”
