Several nations have expressed concerns over the speed of the bobsled track at the 2010 Winter Games in Vancouver.

Some teams voiced concerns about safety at a meeting Friday with race officials. The head of the Swiss team, Markus Wasser, said in an interview that high speeds and gravitational forces at the bottom of the track give pilots no time to correct driving errors.

The team withdrew driver Daniel Schmid for what it called “safety reasons” after two crashes in training. Swiss gold medal favorite Beat Hefti also withdrew from two-man with concussion following a crash on Wednesday.

For luge, speeds were slowed when the start was moved lower down the track after Kumarishtavili’s death on Feb. 12.

IOC president Jacques Rogge, in an interview with The Associated Press, promised Saturday to do “everything in my power” to prevent a repeat of the crash and said the International Olympic Committee will work with the luge federation to “take all the steps that might be needed” to avoid another tragedy at future games.
