Australian Mark Webber has accused Formula One's rulers of being deaf to drivers' concerns about tyre safety.
The Williams driver warned at the Canadian Grand Prix this week that regulations forcing drivers to use one set of tyres for both qualifying and the entire race had made the sport more dangerous.
The rules brought in this season contributed to Kimi Raikkonen's dramatic crash at the European Grand Prix when the McLaren race leader's suspension failed on the last lap because of vibrations caused by uneven tyre wear.
In the past, the Finn would have been able to replace his tyre at a regular refuelling stop.
"I think that unfortunately it won't be the last one we will see," Webber said of an incident that saw Raikkonen's out-of-control car narrowly miss Jenson Button's BAR as he pitched off the track at speed.
"We will see another moment where someone has a problem with a tyre in the race.
"But the drivers' opinions are not very important anyway because we never get listened to.
"Nothing changes really," added the Australian.
"I personally think that running a race on one set of tyres in some cases will be more dangerous for the drivers... when you're leading the race of course you're not going to stop to finish fifth."
The FIA sent a letter to teams last week reminding them that cars could be ordered to pit if their tyres gave cause for concern but putting the onus largely on them.
Under the rules, drivers can change damaged tyres but they must make a special stop to do so. Teams must also prove that the tyre was in a dangerous state.
Webber praised the FIA's race director Charlie Whiting for listening to drivers, and said the tyre issue would be discussed again in Canada, but said their opinions counted for little when it came to big changes.
Webber suggested it would also be better to have a single tyre supplier, rather than the current battle between Michelin and Bridgestone.

Trevor Carlin has stood down as Jordan sporting director, the struggling Formula One team said. Jordan team boss Colin Kolles acknowledged that Carlin's departure "does create a void" but the Briton would retain an advisory role with the team owned by Russian-born Canadian billionaire Alex Shnaider. Shnaider plans to rename the team Midland next year.
