I have been driving at 25,000 miles a year plus for the last 20 years or so and have probably been lucky not to have had my windscreen broken for at least 10 years. However, last Friday it was hit by a large stone or similar on the M4 eastbound between Junction 15 and Membury services. It soon started to crack from the impact point. Dissapointed, I put it down to bad luck. I have been searching around to get it replaced but didn't have time before yesterday (Wed 4 June). I was hit by another object hard enough to make a big impact and crack the screen in a different place. This happened westbound between Membury Services and Junction 15!
This may well be a coincidence (and certainly fortunate I hadn't got the screen relaced yet), but it made me wonder whether there were other drivers who had had this happen in this area and, if so, whether something more sinister was going on.
I still feel fairly sure it's a big coincidence...but time will tell.
