Anyone else notice the second set of skid marks on the road there?

Trucks have wider tires, so wider marks! That seems a car going a bit side ways when braking!

Those are GT3 tires skid marks on the right and those things are MASSIVELY wide, and yet the skid marks are only 4 inches or so across.

If it is another car, do you think he rear ended them causing them to freak out and lock up their brakes or are you suggesting they were going the wrong way down the road?

Yeah your right!

This. But some car on the wrong side of the road could explain the whole accident:idea:!




EDIT: How do they know he was doing 110mph?

Me thinks you don't quite understand the laws of physics. Combined with the fact that these cars are not race cars, a crash into a tree head on at 110mph will obliterate the car.

There is a very good reason that Rally cars have been slowed down and another reason that you will never see an open tree near a race track.

My point was that most super-cars and luxury car-brands are generally as survivable at 110mph (where a 65% survival-rate would qualify as 'should survive'), just as the 'regular' passenger vehicles which get tested at 60mph, are supposed to be survivable at that 'high' end of the speed spectrum. (. . . Just as Formula 1 car drivers sustain 180mph crashes, or 168mph suspension pieces to the helmet.)

Even un-seatbelted accidents at 30mph are 70% survivable.

Perhaps Porsche should make their cars survivable in crashes up to 150mph—the GT3 is intended to be raced, which is also when wrecks happen—and with a car that light and a chassis that stiff, it shouldn't be far from achievable. If you're up to the engineering challenge of making a car go 190mph, you should also consider what happens when it loses control at that speed.

Were he not drunk, and if a deer or something had crossed the road causing him to swerve, this would be a completely different discussion.
 
Robert Ebert is apparently getting flack for what he said on twitter.

It may have been a bit strongly worded, but you can't deny the truth in his tweet.

It would, but if there was an impact they would have been able to tell. Also, they can easily tell if the skid marks are from the same period of time

They can tell how fast he was going from the length of the skid marks and strength of impact.

Race cars don't hit trees (unless you're Peter Dumbreck).

Trees have no "give". Hitting a tree is very bad - I'd rather drive into a house than a tree.
 
^^ That. Trees and lightpoles are unforgivable. Most of the time.

And on the pic of R1600T the car hit the "sidewall" on a really bad place, which could have propelled the car in air and causing it to crash in a manner in which it wasn't concieved.
I was shocked when I saw the wreckage, rarely saw a porsche disinteragted like that
 
More recent ones have been engineered to deform in specific ways in a crash with a vehicle. Nobody's engineered trees.

Ryan could have just freaked out when seeing another car going towards him! His reaction could have made him turn hard to avoid the impact! If it was me and that situation ( because i rarely drink nowadays and never when driving especially with other people under my responsability, in the car that is) i would have turn the car to the other lane pass right by him or simply turn on that exit on the right in the picture! Thats another reason why people shouldnt drink... your reactions and reflexes decrease (depending on how good you really drive, reflexes and of corse how much you have drunk)! A bit subjective:P!


If they do calculate the speed of the car on the impact, do they calculate considering the cars weight vs braking power?




EDIT: I have avoided many many accidents in my life. Once i witnessed an accident by 2 cars that crashed on the highway when they were like 50 to 100 meters in front of me and i had the nerve, reflexes and got lucky enough to go and pass them by the side of the highway (going 160km/h)!

No way to tell what lane he was in from that picture :/ Although even sober most people would swerve and going anywhere near 100 would make that swerve turn deadly.

There definitely ARE ways of including mass and braking power in the equation, but I cannot say with confidence if the police would use that in their equations...Although I wouldn't be surprised if they had a computer that did it for them. IE enter car model and make, length of skidmarks and voila the computer tells you how fast they were traveling.

That would be much more accurate, wouldnt it;)!

To be honest it's quite possible he only locked the fronts.

Even so, stock front tires on a 911 GT3 are 235mm or approximately 9.25" wide - more than double the assumed 4" skids.
