The New Zealand driver Scott Dixon was left fuming with race organisers despite fighting from 18th place to finish second in race two of the Firestone Indy Car event in Texas after a blind draw was used to determine where the drivers would start on the grid.
Dixon and Target Chip Ganassi team-mate Dario Franchitti, who finished seventh after starting from 28th, both vented their frustration after the race.
The drivers claimed the blind draw system was a joke and should be abandoned, with Franchitti furious that pure luck, not skill, determined the grid positions for the second race.
They say if the closely fought championship was decided by the results from the two Firestone races it would be a massive indictment on the sport.
Championship leader Will Power was first in the second race with Ryan Briscoe third behind Dixon while Franchitti won race one with Dixon second and Power third.
