has since returned to the state of Texas, hosting the United States Grand Prix since 2012 at the newly constructed Circuit of the Americas, located in the state capital of Austin. However, the race in Austin has always been held in October or November, away from the Texan summer. The heat also caused some drivers to take some countermeasures to cope with the heat; such as Rosberg's water-cooled skullcap (a common device in the NASCAR circuit); Piercarlo Ghinzani, who finished fifth after overtaking the collapsed Mansell, having a bucket of cold water thrown over him during a pit stop; and Huub Rothengatter, who dashed straight to a spectator area after he retired from the race, where he commandeered several cups of water "for pouring over his nether regions…". Ayrton Senna had retired from the race on lap 47 while running fourth after hitting the wall. On coming back to the pits, he was furious, telling his race engineer Pat Symonds: "I just cannot understand how I did that. I was taking it no differently than I had been before. The wall must have moved." His team did not believe him and Senna persuaded them to inspect the wall after the race, only for them to find that the barrier had indeed been moved by an earlier crash, moving only a mere into the track. Symonds recalled his amazement in 2004, saying: "That was when the precision to which he was driving really hit home for me. Don't forget, this was a guy in his first season of F1, straight out of F3...".
