I have some real concerns with the fact that the windscreen extends beyond the drivers head, kind of acting as a sunroof. Even though it is tinted, not sure how this will go in summer heat situations for the driver and passenger. There is no option to pull a shade blind down on the upper part, much like you do with a sunroof. Not to mention the added strain and use this will place on running the a/c. I know where I live (Australia), that the tinted sunroof is closed for at least 8 months of the year, as the heat issue on the head is too great.
