Drivers question Korea safety
Team bosses and drivers have expressed concern about the safety of the pit lane entrance after the first day of practice in South Korea.
Lotus driver Jarno Trulli said the issue of the entrance, with pitting cars having to slow down abruptly to leave the track off a very high speed corner, would be taken up with race director Charlie Whiting, saying: "It's very dangerous. It is a big issue."
World champion Jenson Button added after the two practice sessions that the turn was "a little bit scary".
"I haven't been behind a car yet when it has pitted, but it's a corner where you're at full speed (250kph) and if somebody goes into the pits they will have to lift pretty heavily," the title contender added.
"That's a bit of a worry and I don't really know how we're going to get round that issue. We'll discuss it and hopefully find a way around the issue."
"The pit entry and exit is a little bit marginal to get on and off the track but, apart from that, they've done a remarkable job and I'm clutching at straws to criticise anything," the Australian said after setting the fastest lap of the day.
German team mate Sebastian Vettel, third overall and 14 points behind Webber, described the entry as "quite on the edge."
"Someone going into the pits will be going slower than someone who is staying out. If you're trying to pass and they decide to pit, it could be quite difficult," he added.
Conditions on Friday were slippery, with the newly-laid asphalt yet to be raced on, and dusty, with drivers kicking up dirt as they probed the racing line and grip levels changing during the day.
"It was the dirtiest circuit I have ever been on," said McLaren's Lewis Hamilton, another contender in fourth place overall but fastest in the day's opening practice. "It was so dusty it was incredible."
That aside, the layout met general approval and team principals used a post-practice news conference to congratulate the host nation for the £141.5 million facility some 250 miles south of the capital Seoul.
"The facilities are obviously very impressive," McLaren's Martin Whitmarsh said. "It's a great commitment and I think everyone is happy to be here.
"I think a lot of fear and concern was spread in the months before we arrived here but I think it's generally a pleasant surprise.
"Inevitably, you can go out there and find some things that aren't quite finished but everyone's been working hard," he continued.
"Korea is a new adventure for Formula One."
