What's the POINT of a glass roof?

[Navsarin]

I don’t know why glass roof as well.
I love our Pano roof and the open air, breeze and nice sunlight through the cabin. Even while parked we keep the pain roof open slightly and let’s fresh air in and keeps the cabin cooler

I could never go glass roof. It’s like a teaser to enjoy air and sun...but you can’t!

Before I bought my Model S I was concerned about whether the sun would heat the interior up to the same sort of temperature at the surface of the sun. (I live in Australia where summer temperatures can get up to the 50 degree mark).
So far no problem, certainly during the fall (which is now).
However, what's the point of a glass roof? I have to admit that I am almost never aware of it - it's always a bit of a surprise when I glance up and see my reflection - usually I can' see anything outside through it.
I would guess that it weighs more than a steel or certainly aluminium roof. It's unlikely to be stronger than either. The insets where the glass is glued to the body must produce extra interference drag by generating vortices. It's got to be less safe in the event of a bad crash. I would also assume that it might suffer damage more readily than a metal panel by stone hits or hail.
All in all, I can see very few arguments in favour of them - but I'm always ready to be convinced!

it's purrrrty.

The main reason is streamlining there manufacturing process.

Are you tall? I'm just wondering since I'm only 5'8" and never notice any heat issue with my sunroof. I can feel a little heat if I hold a hand up a couple millimeters from the glass but if I didn't do that, I would never notice any heat from the glass.

Yes, I am 6 feet and try to sit as high as I can, so indeed my head is close to the glass.
