How are windshields holding up to chips and cracks

[montanah3]

Just curious if anyone has had any problem with window cracks/chips due to its upright design. I was a little concerned about getting my Hummer for this reason. Seems like in this part of the country we get more than our fair share of stones from dirt roads and items flying off the wheels of big rigs speeding down narrow highways. I am thinking about the the Scotchcal installed in certain areas. There is a certified installer near my Hummer dealer. Wouldn't it be nice to have something similiar for windshields.
