Tempers flared at the Las Vegas Grand Prix after the first practice of the USD 500 million race was halted nine minutes into the session Thursday night because Carlos Sainz Jr. ran over a water valve cover that badly damaged his Ferrari. The FIA said Sainz hit the concrete frame around the cover. It took another 11 minutes for the governing body to call all cars off track so it could inspect the entire circuit. (More Motorsports News)
