Drivers seek Singapore track improvements

Although most drivers are impressed with the challenging layout of the Marina Bay circuit, a number expressed concerns about the lighting quality at certain parts of the track during their regular Friday night drivers' briefing with Whiting.

Jarno Trulli, in particular, led calls for modifications to be considered overnight to help improve matters.

"Myself and some other drivers complained about it in the driver's briefing, so definitely there is still some work to do," said the Toyota driver.

"There are some spots that are still quite dark, (as well as) the bumpiness and some kerbs. In general we have been talking quite a lot, well nearly one hour, in the drivers' briefing. It was quite amazing how many things came up after the first two practice sessions."

Renault's Fernando Alonso said his view of the lighting had changed since he walked the track yesterday.

"In terms of the lighting, when I walked the track I was impressed, but behind the wheel at 300 km/h some parts of the track are a bit dark," he added.

Trulli said that the bumps on the track were the worst he had experienced in F1, even though there is probably little that can be done to solve all the track issues before Sunday's race.

His thoughts were echoed by BMW Sauber's Robert Kubica.

"It is pretty bumpy. I think it is even too bumpy but this is how it is," the Pole said. "We have to make some compromise for the set-up because of this bumps. They are making our life much harder."

However, modifications are more likely for the pitlane entry and exit - both of which are on the racing line at the high-speed first and last corners.

Further work may also take place at the Turn 10 chicane, where some high bumps on the kerbs were ground down before first practice on Friday.

Trulli added: "There has been a lot of talk about the pit entry and pit exit because it is quite dangerous. But at the moment I don't know what we can do or what can be done for tomorrow."

Speaking about the Turn 10 solution, Trulli said: "We have gone through this, and maybe there is another opportunity to change it for tomorrow and make it a little bit safer and better."

Toro Rosso's Sebastien Bourdais was also unimpressed by the chicane at Turn 10.

"It's bloody dangerous and I hate it," said the Frenchman.
