Upon hearing of Wheldon's death, Courtney described the accident as a sobering reminder of the dangers faced by racing drivers. As the first major international motorsport event after Wheldon's death, organizers of the V8 Supercars series planned a series of tributes to him at the Gold Coast 600. Wheldon's place was taken by another British driver, Darren Turner, an FIA GT1 World Championship competitor. Wheldon's name was left on the car as a mark of respect, while British drivers at the event paid tribute to him with helmet decals, and several other drivers planned individual tributes to Wheldon. Kanaan, who had also been scheduled to race in Australia, announced his withdrawal from the event out of respect for Wheldon. However, Briscoe, Tagliani, and Hélio Castroneves, all of whom raced at Las Vegas, along with other part-time IndyCar drivers Sébastien Bourdais and Simon Pagenaud, who were not at Las Vegas, did race. Bourdais, the best performing "International" driver, received the Dan Wheldon Memorial Trophy. Sam Schmidt, for whom Wheldon had been racing at the time of his accident, admitted that the events at Las Vegas Motor Speedway had prompted him to re-evaluate his involvement in motorsports. Similarly, veteran drivers Davey Hamilton and Paul Tracy said they were considering retiring from racing on the back of the accident. In the NASCAR Sprint Cup Series, several drivers at the 2011 Good Sam Club 500 at Talladega on the weekend after Wheldon's death put special tributes on their cars, like NASCAR issuing the "Lionheart Knight" decal Wheldon wore on his helmet, which were placed on the cars' b-pillars, along with T. J. Bell putting Wheldon's name on the namerail. Driver Marco Andretti withdrew from The Celebrity Apprentice, which started taping days after the incident, and was replaced by his father Michael, team principal of Andretti Autosport. On December 9, 2011, IndyCar decided that they were not going to return to Las Vegas for the 2012 season. Randy Bernard expressed reluctance to return to the speedway following Wheldon's death, despite the insistence of Speedway Motorsports, Inc. president Bruton Smith (who owns the track in Las Vegas as well as three other tracks used by the IndyCar series) for the series to honor its three-year contract with the track. As of that date, the investigation into the accident was still ongoing. IndyCar was holding back on the release of its 2012 schedule until the investigation concluded.
