The 1978 United States Grand Prix West was a Formula One motor race held on April 2, 1978, at Long Beach, California, won by Carlos Reutemann for Ferrari. He took over at the halfway mark from Ferrari teammate Gilles Villeneuve, when the Canadian crashed out of the lead, and won by eleven seconds.
On lap 39, just before the halfway point, Villeneuve came up to lap Clay Regazzoni, who was in a battle with Jean-Pierre Jabouille’s Renault. Rather than wait until the straight, the Canadian tried to get by in the twisty section leading up to Ocean Boulevard. There simply wasn’t room, however, and, when Regazzoni braked earlier than Villeneuve expected, the Ferrari’s right front wheel hit the left rear of the Shadow and was launched over the white car into the wall. Fortunately, no one was hurt.
