You must not be able to read sir. No vehicles were anywhere near in front of me so exactly how did a rock fly into my window to cause a crack, which by the way has now expanded to roughly 10 inches just sitting in my garage, at 45 miles per hr. You must be one of those Subarus are the almighty king kinda guys but if you took 5 minutes to google 'Subaru weak windshields' you'd see a long list of links where it's clear I'm not the first one who's thought this or said this. Sorry that I'm a first time Subaru buyer who is not use to seeing cracks happen at such a large scale from a rock that seemingly came out of nowhere at 45 mph. I've traveled all over the country and have had windshields hit by massive rocks and various things at much higher speeds and never have I seen this happen. So yes naturally being 1 week into my first Subaru and having this occur leads me to think the windshields suck. Make sense? I can think of times in my travels across country driving through Utah at 85-90 miles an hr and seeing the highway littered with large rocks during a busy holiday travel week. I probably got pummeled a dozen times by large rocks in 20 minutes just passing by semis but my windshields have always had no more then pits put in them. Since 2012 I've probably owned 7 different types of brand new vehicles. Kinda weird how I get a Subaru fresh off delivery from the factory with 5 miles on it and 250 miles later my windshield is essentially ruined.
My point is. Even if a rock hit my window. At the rate of speed I was at and where the possible impact zone is doesn't explain why it created a straight hairline crack starting from the edge of the window 6 inches across then an hr later I check on it again and it's literally expanded another 4 inches but is now starting to curve and make its way downward as it's parked. One could only assume the window must be pretty weak, yeah?
