his collision with De La Rosa. Frentzen reacted by suggesting that Barrichello braked earlier which forced him to make contact with teammate Trulli. Whiting defended his decision not to stop the race saying that the safety car was deployed as all cars involved were in the run-off areas and that he believed stopping the race would be dangerous. However, he admitted to not being aware of Gislimberti's condition when making the decision. Jordan team principal Eddie Jordan believed that Whiting had made the right choice and praised the safety of the modern Formula One car for protecting drivers. Bernie Ecclestone, the owner of Formula One's commercial rights, called for the removal of chicanes from racing circuits labelling them "silly and unnecessary". FIA president Max Mosley subsequently announced that safety measures would be reviewed and stated a review of the Monza track would take place. Mosley believed that no driver was responsible for causing the accident but stressed to competitors that it was their responsibility for being aware when bunched up at the start of a Grand Prix. Former driver Jacques Laffite advocated an electronic warning system for marshals and believed that a review of chicanes should have taken place. Gislimberti never regained consciousness and he was pronounced dead at Monza Hospital. The Trento-born volunteer firefighter and lead water control engineer in the province, who was vice-president of the CEA Squadra Corse firefighting organisation, predeceased his wife of two years Elena (who was pregnant with his child) and other family members. His autopsy released two days later determined his cause of death was head trauma. On 15 September, he was given a funeral at the San Ulderico church, Lavis and attended by several drivers, friends and colleagues. Hours after the race, five cars involved in the accident were impounded by Italian authorities. Magistrate Salvatore Bellomo opened a formal investigation into the crash and interviewed drivers. The investigating body examined all five cars which were released back to the teams on 12 September. The investigation was closed in June 2001 following a technical examination which concluded that Gislimberti was killed instantly. As a result of Gislimberti's death, the strength of the wheel tethers was doubled to stop flying tyres being a danger to the drivers, safety officials and fans. The chassis would be strengthened and enhanced crash resistance would be tested. With his win, Michael Schumacher reduced Häkkinen's advantage in the World
