It is starting to warm-up where I live and my Insight seems to get really warm, I think the glass on the hatch is like a little solar trap. I don't want to run the AC and when I open the widows it is very loud at highway speed. That made me think that the small, triangular windows would be great if you could open them. I had this idea of hinging them like the back (not on the hatch, but next to the passeners in the back row) window of a minivan. Does anybody know much about glass? You would need to attach the hinges to a strong point and then drill the glass, or maybe you could glue the hinges on? Any ideas/comments/suggestions?
