Question: How many times did the man Mari George rode in the pace car with in 2011 win the Indianapolis 500? Passage:In most cases, Tony Hulman would give the command, then ride in the pace car during the pace laps. Mary F. Hulman would give the command near the pace car, but rarely rode in the pace car due to her age and declining health. Eventually, the location was moved to near the start/finish line, and in 2001, it was moved to the new Victory Podium stage adjacent to the Pagoda. In 2011 only, Mari George moved back to the front of the starting grid to give the command, and then she rode in the pace car with A. J. Foyt. In 2014, as a special gesture to Jim Nabors's final performance at Indy, the starting command was given in unison by both Mari George and Nabors, marking the first time a non-member of the Hulman-George family had given the command for the 500 since 1954. In 2016 for the 100th Indianapolis 500, now-matriarch Mari was joined by three subsequent generations of the Hulman-George family, who gave the command together. Due to her advanced age, the 2016 race would be Mari's final turn giving the command. Later that same year, Tony George gave the starting command for the Brickyard 400, his first time giving a command since a restart command in 1986. For the 2017 Indianapolis 500, the duty was permanently assigned to Tony George. In that year, Tony George began using the phrase "Drivers, start your engines" instead of the more familiar "Lady and gentlemen..." variation. However, for the 2019 race, George recited that latter variation.
