Just as you can assume I think he never worked a day to have that car, I can assume you think he worked all his life... what difference does that make? (as if someone who worked all his life to get a car like that would treat it so poorly

).
You're assuming all sorts of things. I'm not assuming anything, just pointing out that there's more possibilities than just "he's a lazy rich prick".
Just because you can afford something doesn't mean you "should" be able to use it as you please. Consider priceless art and the idea might change... suddenly being able to buy the mona lisa doesn't mean you are in the right to destroy it (simply because you could buy it).
In the case of objects that are unique and of significance to the human race as a whole, I agree completely.
But there's not a shortage of F40s. If it was one of the last few, then sure. If it was the last one, it shouldn't even be on the road. But the more of them there are, the less it matters what happens to any single one. Does anyone shed a tear when a Toyota Corolla gets written off?
There were more than a thousand F40s made. It's an amazing car, but the world isn't going to be any worse off for the lack of one or two.
The owner of a historic Ferrari decided to abuse it for the sake of carry camping supplies (maybe) 40 yards from the cabin, then took pictures from MULTIPLE angles (POORLY done pictures at that, no artistry at all), and the internet is suppose to think that's cool or even respectable? I think not.
That owner is definitely an attention whore who would rather be cool on the net than have a proper F40.
So at this point you even agree that it wasn't driven that far on a dirt road, and yet you still have a problem?
Cars have gone through far, FAR worse for the sake of an interesting photo. Do you get furious every time you see the Top Gear boys abusing some exotic as well? Yeah, what he did to the car probably wasn't worth it, but I don't see how it really matters when the likely damage, if any, was trivial and there's that many more F40s out there. Again, his car and his money, he can do what he likes with it.
And you didn't answer the question about Rowan Atkinson? What's your opinion on someone who repeatedly crashes his F1, which is an order of magnitude rarer than the F40? There's only a hundred F1s, and it's arguably a more historically significant car than the F40 as well.
