You have all no doubt heard of and hopefully apply instinctively the 'three second rule' when motoring down the highways at speed.
I saw this news items and thought I'd share - Driving? Always be alert to your surroundings.

Lucky indeed! I still wonder if the three second spacing would have helped avoid the situation at all.A driver has escaped serious injury after a heavy metal beam fell off a truck, bounced then pierced his BMW X5 SUV's windscreen in San Jose, California.......... he not so much dodged a bullet, but dodged a large beam of metal.....
.......... keep a safe distance from the vehicle ahead, and to "always be alert to your surroundings".
