This one is a little weird – it shows the opening Formula Renault 3.5 race in Austria. Roberto Merhi crosses the finish line and immediately slows right down on the right hand side of the grid. Other cars were, obviously, still racing behind him. Nicolas Latifi was fighting to hold off Tom Dillmann for fifth place and upon crossing the line slammed into the rear of Merhi. Thankfully both were able to climb out of their cars unaided.
