The thing is, the previous sunshades were very well built—able to retain a stable temperature between the glass and the interior—and they were made of UV-resistant and heat-reflective materials. Those "hard" sunshades also had a special infrared-reflective coating on top to minimize cabin heating and protect surfaces.
Today, the sunshade is like pantyhose: it does nothing, looks like saggy drapery, and fails to provide the temperature cushion it once did; (add to this also a better sound cushion too). Now, you can see those panoramic screens getting foggy or developing moisture build-up due to the lack of thermal insulation (please read: BMW cutting corners).
If I leave my older, warm vehicle outside in winter, there’s no issue. But if I leave my new X4 outside in the same conditions, you can see moisture build-up—definitely not good. Older BMWs used better insulating materials (e.g., thicker carpets, treated headliners, hard sunshades), which helped buffer against rapid temperature shifts.
I have both, and I can tell you that older BMWs were far better in terms of quality and thermal protection in both scenarios—cold or hot. I wonder if today’s cabrio carpets are still UV-resistant, colorfast, moisture-resistant, and woven with reflective fibers.

What if we put the tint on the exterior?

You will be replacing it often.

Porsche does it best. You can set the regen to Auto, so it behaves like the adaptive regen in the BMW. But you can also turn it off, so you can just sail and recuperate with the brakepedal if necessary.
It's also more efficient. sailing > recuperation > braking

This is going to be the new benchmark.
