Formula One world champion Lewis Hamilton took a swipe at Singapore's street circuit before qualifying on Saturday, calling the city-state's track "very dangerous".
The McLaren driver, out of contention for this year's title, complained that the road circuit is dusty and bumpy and that improvements promised last year had not been implemented.
"It's such a bumpy track and the ride on our car was quite poor," Hamilton told reporters in the paddock at the Singapore Grand Prix.
"It's shaking so much. The car is bumping and bouncing and sliding. It's still very bad. I don't really think it's changed at all to be honest."
Hamilton also hit out at changes made to the chicane on turn 10, where curbs have been built up.
"It's a lot worse than last year," Hamilton said. "Last year, it was a weird little corner anyway but it was quite good -- a quick left, right, left. Now it's big, fat curbs and there's no runoff, so it's very dangerous.
"I'm sure in the race someone will crash there. If someone blew a tire and had an over-steer moment and slid and hit one of those curbs, they would fly. It's not very safe."
Hamilton said these issues had been raised at the drivers' meeting on Friday, and the sport's governing body the FIA would be asked for further improvements for 2010.
