I had one of these moments happen to me today.

I'm in the far left lane of a 3 lane highway. i decide to move into the middle lane and right after i check the blind spot and start making my move over, i look ahead and see a 4' by 4' or so piece of plywood come cartwheeling out of a truck that is in the middle lane a few car lengths ahead. after a quick swerve into the right lane, i watch it go by my window.

for doing about 70 the X handled it really well.

it was closer than i would have liked but accident avoided.
