Drivers concerned about Spa safety

Several drivers complained about the revised pitlane entry, which they claim is too tight and blind.

However, Honda's Rubens Barrichello reckons some of the run-off areas are also too small at crucial parts of the track.

"It is one of the best tracks in the world, I really like it. That is why something has to be done about the safety," Barrichello told autosport.com at the end of testing. "We cannot have that pitlane entry, I just hope something bad will not happen here.

"But not only that, the track needs more run-off space, it is just not enough. I just hope nothing will happen. I am just concerned."

Toyota driver Jarno Trulli agreed with Barrichello that some run-offs were not big enough, and insisted the pitlane entry will need to be changed in time for this year's race.

"Everything is more or less good. There are some safety issues on some very high-speed corners like Eau Rouge or Blanchimont," said Trulli. "It would be nicer to have more run-off area in those places, but the rest is okay.

"The only down point is, like everyone says, the pitlane entry and the pitlane exit. It is a bit dangerous. It is better to have it changed. It is very narrow. An F1 car cannot go through there.

"If someone misses there and crashes into the wall no one can pass, no one can come in."

Super Aguri's Takuma Sato added: "The pitlane is very narrow, so if a car stops there, there is no way other cars can pass, and also it is blind.

"It is a bit hairy really, but at the last corner there is so much space, even after the turf has been put on there does not need to be so much space in that corner. So we can enlarge the pitlane so at least two cars can pass."

Red Bull driver David Coulthard confirmed to autosport.com on Thursday that the Grand Prix Drivers' Association had written to the FIA in regards to the pitlane entry, and that FIA technical delegate Charlie Whiting had acknowledged the letter.
