extra stress on the Mexican Grand Prix committee to ensure the track was ready for 1992. Some safety measures had been implemented to the track, including further easing of the banking at Peraltada, making the corner a little slower; this was done to avoid bypassing the entry to this corner via making an alternate route to the middle of the Peraltada through the park's baseball stadium. Although the circuit was popular with drivers, they complained during interviews with the press about the ubiquitous and severe bumps on the circuit, which had decayed even further and were worse than before - even the Peraltada was very bumpy and Mansell nearly crashed there during practice. Despite these concerns the race that year went ahead, and saw Williams teammates Mansell and Patrese dominate the race. Senna had another bad accident during practice, this time at the fast Esses- Senna went over a nasty series of bumps that unsettled the car to the point where Senna lost control, went off the track and hit a concrete wall; he had minor injuries but qualified 6th and took part in the race. But the state of the track, the decline of Mexico City itself, not only with air pollution problems but also a rapid and unstable city population increase saw Formula One leave again. Absence (1993–2014) 2002 saw the revival of the Grand Prix of Mexico for Champ Cars on a much modified version of the Autódromo Hermanos Rodríguez circuit which included cutting the Peraltada in half. This was a six-year stay which saw Sébastien Bourdais win half of the six races that followed. Rumors first surfaced in 2003 that the Mexican Grand Prix might return to the Formula One calendar at a new $70 million circuit, dubbed "Mantarraya", to be built near Cancún. In 2005, the governor of Quintana Roo state said that Mexico would have a Grand Prix on the calendar for . The plan was halted later that year as a debate arose about whether the land the circuit was to be built on was properly owned by the right people to do so. After the 2006 United States Grand Prix, Bernie Ecclestone announced that the Grand Prix of Mexico would return for the season, but nothing further came from the announcement. Return to the Autódromo Hermanos Rodríguez (2015–2019, 2021–present) In August 2011, Carlos Slim Domit revealed plans for a revived race. In
