How do you know that was an automatic downshift and not a driver overcorrection or even a lump of ice that woke you up? From the pics, it looks like the MB lost control around the corner on ice or snow, and slid into the limo's lane.
How do you know for sure that both vehicles accelerated into the accident? As you said, you were asleep less than 2 seconds before.
Is the curve blind? How can we assume that the drivers of both vehicles even saw each other 2 seconds prior to to impact?
How do you know how fast the limo was going? As you said, everyone thinks its a high speed accident, curious how you are establishing this fact
How do you know how fast the MB was going? Same as above
Im not asking these questions to defend MB or attack you, but Im trying to figure out how you have established these factors, especially in relation to filing a successful lawsuit. You said yourself you were A, asleep, and B, unaware that you were even wearing a seatbelt until much later.
It would be childs play to create doubt that you knew what speeds the accident took place at, what downshifting was taking place, or generally what was going on before or during the accident. This is IF, your memory is the only evidence you have of these things happening.
To defend against your opinion, id just have to ask how you can know the vehicle downshifted and not know that you were wearing a seatbelt, especially if whatever it was that woke you took place mere seconds before impact.
Unfortunately, from what you have written, it seems almost impossible that you could successfully sue MB without additional proof of these factors.
Even a demonstration crash test does what? You are not recreating the events of the crash, but crashing vehicles into a solid barrier based on how you think the crash took place unless you have other evidence. To defend against that, all a defense attorney would have to do would point out the differences, and ask similar questions to the above questions.
I can guess that the way MB would defend itself would be to say, as the pictures seem to suggest, that the driver of the MB was speeding, lost control around a curve, drifted into the other lane, and crashed into a limo. How and why and what are unknown factors, but what is definitely known is that both cars are destroyed in such a way as to suggest high speed, and that the MB is in the wrong lane, and that conditions were poor. Then MB would say the two passengers not wearing seatbelts were killed, and the one asleep immediately before the accident and wearing a seatbelt was severely injured, yet lived. Then they would say that the survivor of the MB is understandably upset and looking for a source to blame.
Unless you can prove to a jury definite concrete facts of speed, what was going on, downshifting, the above scenario would be hard to successfully attack, and I would imagine a Jury would easily believe that a high power sports car driver lost control around a curve at speed and caused a huge accident. That theory is supported by the pictures, unless you can prove otherwise.
The final most important question is WHY are you posting this topic while the specifics of the case are not yet resolved?
ANY lawyer would tell you to say nothing to anyone about anything concerning your case, yet you are posting away on a forum. What you are creating is a chain of discoverable evidence for MB.
Look at it objectively, they could easily portray this and other posts as evidence of someone who has been severally emotionally and physically distressed by this tragedy, has understandable motives, yet these same motives are ultimately misguided and represents what he wished happened, not what did happen.
If I were you, I would discuss the presence of this and your other threads with you lawyer, see what he/she says you should do, and perhaps delete or remove them until the case is settled one way or another. Im not a lawyer, but its certainly possibly that posting these pictures on a public forum could make them inadmissible as evidence for the case. Your first priority should be to talk to your lawyer about this thread and other posts concerning your case, and do what you can to protect the case, not prove your point on a forum.
