I just missed a large bit of plastic that flew off a buggy that an estate car had tied to its roof rack on the M2 the other day, thought it was going to hit my windscreen, but luckily the wind took it over my van.
It all happens so quickly that your virtually unable to respond to it.
Unfortunately I think your going to have to put this one down to an experience, unless the traffic wombles come up trumps on the video.
