When we make the drive to/from Montana/California in winter or spring, our vehicles get hammered. People will pass, then cut back in front of you wayyyy too close and nail you with a lot of rocks. I will actually put on the brakes pretty hard to minimize the damage when it happens (increase the distance). Windshields, paint, headlights all get hammered. Sucks, but its just what people do. My wife's Mercedes had a new windshield put in last year. $1000 friggen dollars out of my pocket.

Another thing to look out for is someone coming off a gravel road and merging into your lane in front of you. When they hit a certain speed - around 50-60, the rocks start coming out of the treads. Be careful of that.

Denis - many insurance companies these days will pay for chip repairs at no cost to you. Might be worth calling your insurance agent.
