The Indianapolis 500 has been run 99 times in the past 104 years. Beginning with the very first Indianapolis 500 in 1911 a pace car has led the field to the green flag. During the previous 98 races there have been some odd, improbable and just plain goofy vehicles selected or modified to lead the field, but the Indianapolis 500 established the role of the pace for the race and all other circuit-style races.
