My commute route has been a bit unkind over the years to windshields. My Xterra is going to be 16 this year, and has been through 3 new ones since we moved here 10 years ago (none prior). My wife's car has had 1 replaced.
The FR-S had escaped this fate for a long time - about 11 months. I'm also extra careful in it to give cars in front extra room so rocks they kick up are less likely to hit me.
This Monday, I was in the left lane cruising along and a commuter bus moved over in front of me so he could pass a truck. He jumped over closer to the front of me than I would've approached if I'd been following him. As he moved, I heard the fateful TICK! sound of a rock hitting glass. Sure enough just above my center of vision, a 1/4" long crack.
That was bad enough, and I've been waiting for that crack to grow to cross the glass once it gets some hot/cold cycles. Then today as I was coming home, in the left lane about 75mph with some traffic, some asshat in a Chrysler Concorde comes hauling ass up the right lane trying to pass as many people as possible. He wasn't going to get anywhere as there were about 5 cars in front of me. He got just in front of me, hit the turn signal, jumped into my lane, and hit the brakes, causing me to brake hard. As he crossed in front of me, again TICK! and I see on the passenger side a 3/8-1/2" crack in the glass.
I pointed at the crack, flipped him the bird, and a WTF? shoulder shrug. He just kept tailgating the car in front of him. I prayed to the god of kharma for him to get free of traffic and go past a CHiP at 85. Didn't happen unfortunately.
So I'm expecting to need a new windshield in the not distant future. Drowning my sorrow in a glass of wine now.
