I'd bet you Ryan Dunn was street racing when he crashed

[pavyracer]

Notice there are two sets of tire marks. The ones on the right are his Porche which hit the guardrail and then went airborne and hit the tree and was engulfed in flames. But there is a second set of tires to the left.

[Deuce]

So the tires to the left, he was either stomping on his brakes or taking off from a stand still. The car next to him would have done neither because the reaction to Dunn crashing, the tire marks from braking would be near the overpass by the time the second driver even noticed Dunn crashed. Also, when cars brake, even though they have 4 tires, there are only two sets of tire marks not four. Just a thought.

[blackbeSSt]

with 4 evenly spaced tire marks in the left lane? and what are the 2 things that make skid marks? braking and accelerating. unless the car in the other lane skidded to a stop in a straight line, he wasn't racing.

[Extra Innings]

interesting

[OneLossParlayGuy]

its a horrible tragedy, and it sounds like he was drinking earlier that night....thank god he didnt hit anyone else

[pavyracer]

Maybe he tried to pass a truck with rear dual tires and lost control and hit the guardrail and the truck with the dual tires hit the brakes at the same time to let him pass him and won't crash.

who cares

Nothing against truck drivers but I could see them running a Porsche Porsche 911 GT3 off the road...either way he was drunk and driving irresponsibly.

I care...interesting to get an engineers perspective...would have never considered it myself.

Yeah. The four tracks to the left have to be a truck, either one that slammed on its brakes once he saw there was a burning car in the woods or he was in the left lane and Dunn has to swerve him and hit the guard rail.

again, no way even a dually or 18 wheeler makes 4 evenly spaced straight marks on the road.

the spacing is all wrong for a big truck. it woulda left 2 on the left, nice space, and then 2 on the right

Dunn could have also being driving erratically and the truck driver decided to slam his brakes if Dunn was following too closely which caused Dunn to swerve to avoid him resulting in him hitting the guardrail.

True, though they could have seen the fire a ways back and didn't have to slam on the brakes making it possible to have even tracks.

yeah but 4 even tracks? think about how the tires would have to be in order to make those.

think of this as looking at the back of a normal trucks wheels (disregard the underscore):

now a dually:

wtf out there could make something like this?

I am reading reports that they found his car 40 yards through the trees fok

[Cuse0323]

yeah it's pretty strange, four evenly spaced tracks in a straight line. who knows what really happened.

We'll find out sooner or later. Police can identify tire types and surely they will audit records for truckers who commonly drive that route at 3am. I would be on that road for the next week taking plates.

That's also possible. The skid marks could have been done by two separate vehicles. The first vehicle that left the skid marks could have been involved in the accident and the second one could have been done later when a passerby noticed the car fire. But it's too symmetrical to be random skid marks from two different vehicles. Notice they both stop at about the same point. That means both vehicles left the same distance skid marks off by a few feet in a straight line.

Get to the bottom of this paver and report back

[Deuce]

It is quite possible he was cut off looking from a different angle.

[Cuse0323]

It is a short picture, so the back end of a truck could have swung but we don't see it.

[LostBankroll]

This is tough did he really pass?

Yes, going 110mph and not braking, going 40yds through a forest, most definitely you pass.

[Deuce]

Also, two things I noticed. It appears to be a highway that ends (notice the traffic light). Those tracks may have been from a tractor trailer locking its brakes nearing the end of a highway. We may be looking too far into the tracks. Secondly, right lane ends, Dunn may have been passing someone and lost control.

[Cuse0323]

He also could have been trying to brake and get off on that exit now that I think about it.

Possibly, which would explain the third tire mark. Third mark would happen if he was trying to turn, speed overcompensated and he lost control.

Yeah none of the marks ever go back in the other direction like he was just trying to swerve someone on the left, looks like he braked and tried to get off but couldn't make it and went right into the rail.

Possibly the third mark was when the passenger viciously shit himself upon realizing he was going to die in a couple seconds

This is a head scratcher for sure. In looking at the 2 above pics, I myself am ruling out a 18-wheeler. If a 18-wheeler pulling a trailer did this, there would have been several sets of tire marks from both the trailer and the cab. If it was a single cab only, I think there would have been a incosistancy in tire tracks also. I am thinkin this was the end result of some sort of road rage. Possibly Ryan cuts off a redneck dually puckup truck. The dually speads up cutting Ryan off, and the start of road rage ensues. The dually travels at a high rate of speed with Ryan in pursuit and the dually slams on the brakes. Ryan slams on his brakes and swerves leading to the crash. It looks like the dually skid marks are about 40 ft give or take a few as the white center stripes are usually 6 ft long. There appears to be 3 total, plus the space inbetween each stripe which is around 10 ft each.

I respect your opinion, but I think something else happened. I think Ryan was being chased by aliens and when the spacecraft closed in on him, he tried to shake them off, but lost control of the car.
