An Australian driver apparently angry with being held up by a group of cyclists -- which included a number of current and former Olympians -- slammed on his brakes in front of the group, causing a massive wreck Thursday morning (May 8th) in Sydney.

"We're so lucky somebody isn't dead," former Olympian Ben Kersten told a reporter. "We were pushing 60kmh, sprawled all over the road with trucks going past. I really don't know how someone isn't dead, that's all I can say."

The group was on a training ride about 6:30 am when, according to witnesses, a driver frustrated with being held up by the cyclists suddenly accelerated past the riders, then slammed on his brakes in front of the group, giving the riders no time to stop.

The riders piled into the back of the car and into and on top of each other, causing a chain-reaction of accidents, including a jack-knifing tractor trailer behind them that narrowly missed skidding into the group.

Police reportedly have solid leads on the identification of the motorist who caused the hit-and-run accident, and will be pursuing charges against him.
