All that aside, I'm against canopies for F1 cars...

The FIA did tests recently using jet fighter canopy (links probably somewhere in this thread). So I believe he was basing his assumption upon the thickness of a F16 canopy which are a bit over 1" thick.
I also don't think the thickness of car windshields factor into this at all. They are to prevent wind and weather from getting into a vehicle and are not safety devices. It takes relatively little effort to penetrate one. Anyhow thickness is pure speculation unless someone here has experience in designing this type of thing. And I suspect that most of the experience in this area probably would be military or industrial in nature.
