IndyCar is fairly new in America; founded in 1994 and affiliated in 1996. Driver safety has been a major point of concern, with a number of drivers seriously injured, particularly in the early years of the series. There have been four fatal crashes in the history of the series. Compared to road racing venues, the lack of run-offs on oval tracks, coupled with higher speeds due to the long straights and banked turns, means that there is far less margin for error. Following a series of spectacular high-profile accidents in 2003, including American racing legend Mario Andretti and former champion Kenny Bräck, as well as the death of Tony Renna in testing at Indianapolis, the IRL made additional changes to reduce speeds and increase safety.
