    Of course, let's just all forget it as a ridiculous statement.

    First off, it is a tragedy that something like this happened.

    Second, you don't need to be in a fast car for this to happen, just the right angle...and the right tree.

    Just remember....even at 10mph in a 3600lbs car = 36,000 lbs of Newton Force...
    F=MA

    Crashes are measured in Delta-V.

    That makes sense, because it's not necessarily the force but the change in velocity, although the force exerted between the colliding objects is a big part of that equation. (thrust)

    Of course it makes sense. Different objects that collide with the same automobile at the same speed will exert different force back upon that automobile and cause a different change in velocity.

    Seen a few cars split in half like that. A pro hockey player (Danny Heatley) lost it in his Ferrari 360 and crashed into a stone wall. The car was torn right in two. Heatley survived but his passenger, a teammate, died.

    http://img.coxnewsweb.com/B/08/34/93/image_193348.jpg

    There's also the famous Enzo crash on PCH in Malibu, where that car split in half after flipping or rolling due to the failure of an aftermarket rim at high speed. The driver walked away.

    And there was the Challenge Stradale owned by "Mask" of TapOut clothing, who was killed when his car hit a lamp post at high speed and tore in half -

    When you're going that fast (100-ish) and you go sideways, and there is a thin tree, or a wall, a utility pole... or a lamp post... it's like a hot knife through butter.

    Thanks for the physics lesson guys, I'm a math minor, not a physics major Click here to enlarge

    A bit off-topic, but how does delta-v or delta-p interact with external forces?

    sorry i can't explain it in english but maybe this will help you
    Delta-(P)=m.Delta-(V) ===> Delta-(P)/Delta-(t)=m.Delta-(V)/Delta-(t)
    and we know Delta-(v)/Delta-(t)=a
    ===>Delta-(P)/Delta-(t)=m.a
    and m.a=F
    ===> Delta-(P)/Delta-(t)=F

    I wasn't going to say anything but ...

    The police said alcohol and speed were factors. Do they ever say anything else? This is more of a canned response than anything. Until they find the exact cause, everything is speculation. It could have been wet roads. Or someone running the driver off the road. We don't know. And frankly, I don't care to speculate.

    What we do know is that Daniel died. My condolences go out to his family and friends. I can only hope he went fast, without too much pain and horror.

    Second, yeah he was probably going fast when the car hit the tree. But you can do this in any car. They are not as strong from the side as they are from the front. Who knows how much it takes to split a car in two from the side. It's one thing to throw around equations. But without knowing the structure and properties of the materials and running this through an FEA program, I don't have any idea what the minimum speed would be that would split the car like that.

    We can all pretend we're better drivers and berate someone for losing control of the car. But you're going to feel pretty stupid when it happens to you? If you're living.

    It probably makes more sense to post this in one of the other forums where they talk about Daniel, but I think folks here will take this a little better. Thanks for reading my rant.


    Cheers.

    I personally totaled my '08 335i and as much as I wish I was doing something cool like drifting around the corner while racing a lambo, it was just a combination of poor all season tires and a bunch of weight in the trunk that shifted due to being not secured. Well said ersin

    Don't know about alcohol but looking at the extent of the damage to the car is a clear indicator that speed was a factor. The accident investigators will be able to get a pretty exact idea of how fast the car was going when it crashed by checking skidmarks and comparing damage to similar wrecks, plus the freeze frame data from the "black box", if that survived.
