Manhole Covers and Race Cars
Because of their aerodynamic design, modern racing cars create enough vacuum to lift a manhole cover off the ground. During races on city streets, manhole covers must therefore be welded down to prevent injury. In 1990, during the Group C World Sportscar Championship race at Circuit Gilles Villeneuve, located in a public park in Montréal, Quebec, a Brun Motorsport Porsche 962 struck a manhole cover that was lifted by the ground effect of the car he was following, a Courage C24 Porsche, causing the Porsche to catch fire, and with the safety issues, the race ended shortly afterwards.
