I've had a couple of hairy experiences with road debris being flung up by vehicles ahead of me, striking my car. It's no fun at all, and often very scary because one can't always turn the wheel to dodge the oncoming missile. A few years ago, Miss D. and I were in a rented vehicle on an interstate when a truck ahead of us kicked up a large piece of gravel. It seemed to move in slow motion as we watched it coming right into our windscreen, as if we had a bullseye target painted on our car. There was traffic on either side of us, so we had nowhere to go. It put a large, star-shaped crack in our windscreen as it bounced off with a heck of a bang. (Fortunately, we always pay for extended insurance cover on rented vehicles, so we were able to hand in the car and get a replacement with no financial penalty. Useful, that!)
I was reminded of that by this video clip.
That's far from rare, of course, as this report reminds us.
Be careful out there, friends . . . and if you're carrying anything in the load bed of your pickup, please, please tie it down securely!
