[TRIUMPH TERROR]

Green being considered bad luck started in Indy car racing as a driver was killed,

read this:

So I asked one of the most knowledgeable guys in the garage: the venerable Chris Economaki. Economaki is editor emeritus of National Speed Sport News, a popular weekly racing publication that has been in existence for 68 years. Economaki explained that in the 1930s and up until the end of World War II, no driver would drive a green car. “It was a pronounced no-no in American racing,” said Economaki.



But how did this come about? “We researched this extensively, and the only thing we could find out was that the first speedway fatality was one of the Chevrolet brothers in California who was killed in a green car. And it was the first accident that killed two drivers. Two drivers had never been killed in a racing accident before. ... That led to the superstition that green cars are bad luck.” .........................................................

I hope this helps.....................
Alot of superstitions have came from the auto racing world and have been around for many years.Peanuts and number 13 are all bad luck to the Indy car drivers also.If you look back thru the history of the Indy 500 you will see up until modern times there were no green cars.The only reason today there are green cars is because the money out ways the superstition and for enough money somebody would drive a tittie pink car if asked to.

More on peanuts and green I found that most the superstitions have grown like urban legends over the years and once again most can be cured with the almighty dollar when perteining to motorsports.

It is considered back luck to eat peanuts at the race. Peanut shells were found in the seat of a crashed car in the 1940s.

Many drivers will not drive a green painted car. Until the 1960s, few green cars even showed up at the track. The most recent green car to win the race was Jim Clark's, all the way back in 1965. Certian green cars have been riddled with bad luck.
