Windshields..

You know they make these things, obviously to protect us from flying debris on the highway, roads, other drivers, but why can't they make something to protect it?? I would say within in the past, oh 5 months, I've gotten 3 HUGE rock cracks on my windshield!!!! WTH!!! Why my windshield?? Why not the dude next to me? Is my car a target for rocks?? Do they spread the word that my windshield is fun to hit and that it pisses me off?? I don't get it. My windshield looks like trash now and with the heat we have down here, I'm sure those cracks are bound to spread...ugghhh whatever
