3 Legged Thing has been thinking along the same lines, and the result is the Window Mount Clamp, which as the name suggests, clamps onto vehicle windows (or similar edges that are less than 20mm wide) and has a standard 3/8”-16 screw mount on the top, onto which a variety of different tripod heads can be attached. The clamp affixes to the window or using a screw mechanism. A soft-to-the-touch rubber lining protects the window or other surfaces to avoid marks or scratches.
