So, "a friend" stopped by the accident scene yesterday (It's just a coincidence that I happen to have the same car). "He" approached in the same direction the GT-R was travelling, got out and looked around, then drove down and made a U-turn and came back the same direction as the Lamborghini...
Speed limit is 40 mph, which is what he did in this video...
For obvious reasons, he's not posting his faster runs, but let's just say he was able to do the same thing at 80, and again at almost 100... with no problem.
She must've been flying...
Of course, that is just my opinion.
