1978 United States Grand Prix West

Carlos Reutemann took over at the halfway mark from Ferrari teammate Gilles Villeneuve, when the Canadian crashed out of the lead, and won by eleven seconds.

At the start of the weekend, though only 22 cars would make the grid, there were 30 entries, requiring a one-hour pre-qualifying session on Friday morning for the eight non-FICA members.

Niki Lauda, who had placed his Ferrari on pole for the previous year's race, again set the early pace, this time in a Brabham.

The start had been moved from in front of the pits on Ocean Boulevard to the curving "straight" on Shoreline Drive in order to avoid another first corner tangle.

Andretti was dropping back in fourth, having chosen the wrong Goodyears and a poor top gear, and Jones was closing on him quickly.

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.

Reutemann cruised to the finish, maintaining a twelve to fifteen second gap over Andretti, who had a similar cushion over Patrick Depailler in third.
