I think my 370z is done for...?

KCZ

If I'd just heard the story..."I hit a truck that was abandoned in a passing lane around a corner in the dark"...then I'd say it's the truck owner's responsibility. But having seen that video, where the truck is visible well before the curve, where there's no other traffic in the right lane preventing a swerve, and where the video makes it appear there was time to avoid the truck, now I'd have to say the responsibility is on the OP. Should have left that video under your car seat.
