Formula One is trying to recover in time for its Las Vegas Grand Prix race after an embarrassing opening-night debacle stopped the racers' first practice after just nine minutes.
Ferrari said a car driven by Carlos Sainz Jr. was severely damaged after a manhole cover came loose along the temporary street course late Thursday night.
Workers rushed to remove every drain cap along the nearly four-mile-long track, filling them with asphalt and sand. By the time the next practice started, 2 1/2 hours late, attendees had been ordered to leave the fan viewing areas. The course had to be closed a few hours later, by 4 a.m., in order to reopen the streets to morning commuters.
