Sebastian Vettel flays FIA's revised radio restrictions

Ferrari's Sebastian Vettel has launched a scathing attack over Formula One's revised radio rules, describing it as a 'joke' and also questioned the new track limits in Hungary.

Announcing a change in the new radio restrictions for 2016 season, International Automobile Federation (FIA) had said that it was mandatory for the teams to pull drivers into the pits or retire the car if they inform them of a potential failure.

The move came after F1 leader Nico Rosberg was asked to 'shift through' his gearbox to allow him to continue at the British GP, thus resulting in a 10-second penalty.

Downplaying the incident, Vettel believes it was quite entertaining as a spectator to hear the driver and the team panicking on the radio at the same time, news.com.au reported.

The issue of track limits has been another concern in recent races, with the 'sausage' kerbs in Austria resulting in several crashes while Mercedes' Lewis Hamilton had his provisional pole time deleted for running off-track at Silverstone.

As per the recent FIA's rule, the electronic detection systems would be used to stop the drivers exceeding track limits on turns four and 11 at the resurfaced Hungaroring.

Blaming the F1's governing body for the same, the four-time world champion said the FIA are responsible for building circuits where cars often get off the track.

Vettel, who is currently standing fifth in F1 standings, will aim to catch up his rivals in this weekend's Hungarian Grand Prix.
