I remember a show on the Discovery Channel that indicated James Dean probably never saw the other car due to a mirage effect from the highway. It was quite a while ago so I might have the cars switched as far has who couldn't see who, but I'm pretty sure it was Dean who couldn't see the other car. They used a computer to reconstruct the roads and conditions at the time of the crash. They concluded that it was a freak kind of thing that caused the accident. Not really anyone's fault.
I did some searching on the web regarding this issue.
The first thing I noticed is that lots of James Dean fans have lots of different stories about the incident. In some stories Rolf Wutherich, his mechanic dies in the wreck, in one report he has only minor injuries, in most hew suffers a broken jaw and leg but lives and many years later (1981) dies in a car wreck in Germany. In one account the driver of the other car is never identified by the police for fear of retaliation by Dean fans, in another account it was a farmer driving a truck, but in most accounts he's identified as Donald Turnupseed a Cal Poly student driving home for the weekend. Turnupseed's car is usually reported to be a Ford, often a Ford Tudor, one said a '46, others said a '50. In some accounts Dean didn't see Turnupseed, in others he did. In some accounts Turnupseed didn't see Dean, in others he did. In some accounts the collision was head-on, in most it was a glancing blow. In one account Dean was wearing a seatbelt, in most he was not. By all most all accounts he died on September 30th 1955.
So after sifting through all of the conflicting, unofficial, Nth hand information I could find on the web, here's what I came up with.
Did Dean See Turnupseed's Car?
Several accounts report that Dean did see Turnupseed's car, and said to Wutherich something like "That guy has to stop!" This is in several of the accounts I found, and seems to have been something Wutherich reported after the accident. So I believe that
Dean did see Turnupseed's car in plenty of time, but didn't expect it to turn in front of him.
Did Turnupseed See Dean's Car?
Most accounts also report that Turnupseed tried to stop, and skidded 30 feet. Unfortunately, it seems as if he was already in
Dean's lane when he was skidding (too bad ABS wasn't around then). So it seems that Turnupseed did see Dean's car, at least in the last couple of seconds.
Who Was At Fault?
The police blamed Dean because he was going a reported 85-100 mph. But it's pretty clear that Turnupseed was making a left turn in front of Dean.
A company called "Failure Analysis", now known as Exponent, did a computer reconstruction of the accident several years ago. hat's the sort of stuff they specialize in. They concluded that Dean was not speeding at the time of the accident. They don't have much info online, but what they have is at
http://www.fail.com/...cases/dean.htmlMy take on it is that Dean was speeding. Another driver (John R. White) reported that Dean had passed him at about 85mph just before the accident. However, Turnupseed did turn in front of Dean. I suspect that the small size of Dean's car made Turnupseed think it was farther away, and Dean was moving faster that Turnupseed thought. So Turnupseed thought he had plenty of time to make the turn. When he realized he didn't, he panic-braked and skidded straight toward the oncoming Porsche. Dean *almost* managed to avoid Turnupseed's Ford Tudor, but was struck a glancing blow, which was enough to knock the 1500 pound Spyder out of control. Dean and Wutherich didn't use the seatblets that were in the car. Wutherich was thrown clear and survived (I'm surprised I've never heard this accident cited by people who think not wearing a seat belt will save their lives). Dean stayed in the car, but suffered fatal head and neck injuries, probably from hitting the dash/windshield/hood.
I don't know the details of Exponent's claim that Dean wasn't speeding, but that sort of thing is their expertise, so I'd tend
to have some respect for their finding. But if they say he was below the speed limit at the time of the accident, and he saw the
Ford starting to turn in front of him, he probably had time to brake and lose some speed. So I suspect he was well above the
speed limit when Turnupseed started his turn.
Bottom line: Turnupseed misjudged the time he had, or didn't see Dean until he had already committed to the turn. Had Dean not been speeding, there would probably have not been a collision. The jury blamed Dean.
