Me too and agreed.When you drive them back to back there is less noise of all kind - road noise, exterior noise and so on. Just quieter overall.
This is because with the noise insulated glass the glass absorbs much more of the sound and causes fewer reflections. So it dampens all sounds. Higher frequencies are damped more than low rumble, but even low rumble is lower.
Specifically it takes out the "hum", which is just 2nd and 3rd order reflections bouncing around the cabin.
The difference is massive when you try two of the same cars with the same size wheels and tyres back to back. I drove the exact same route on the same day and the difference was enough that I would never get a CT/ST without the insulated glass.
