People who are not familiar with cars like this have no idea how fast they can get away from you. Just cruising around, with a little extra pedal on occasion, is easy. But if you are slightly behind the curve, and you tip in just a little too deep leaving a stop, things just EXPLODE! Your first impulse is to to brace yourself, and for most people that means both feet clamped to the floor. Guess what's between your right foot and the floor? And then the g-forces keep you braced. Most likely this person was not prepared for what he unleashed. And he was probably tired and a little impaired.
Sometimes my current Mustang catches me off-guard. Happened Saturday, with a short window in traffic straight to an on-ramp, it overpowered the traction control and got out of shape a bit, surprised me. The lambo has over twice the power-to-weight ratio. Just because someone can afford an exotic doesn't mean he's capable of handling it.
