I did discover something interesting, check out the back seat, in the trunk area, and you'll notice when you pull back the thin piece of cloth protection that there's a large gap the entire width of the car opening under the seat and it's in no way insulated. I stuffed some insulation matt into the gap and OMG afterward, while driving, the bass from the subwoofer in the rear came alive in a way it never had before. WoW!

So, then I ran my fingers along the edge under the backseat from the front side and discovered ANOTHER gap the entire length of the car. This could be where a lot of the road noise is coming into the cabin. I'm not sure, so tomorrow I'm going to fill that gap with something as well and see what happens. My fingers are crossed.
Can you take a picture of the spots mentioned, I'm not exactly sure which places you're talking about.
And I love insulation ;)

Can you provide pictures? Also, please let me know how you insulated the wheel arches.
These are the rubber strips (from Ali Express) that I have added:

If you search for them on Ali Express, use the following key words:
rubber strip large D
rubber strip small D
rubber strip Z

I don't have picture of the wheel arches. Had them put in before thinking about taking pictures.
I just added bitumen sound deathning plates to the top of the plastic covers in the wheel arches. You have to remove those before putting it on.
When you jack up the car (one wheel position at a time) you can quite access them quite well. It is quite a lot of work, but made a significant difference. Also when the covers are out you can add some bitumen to the metal of the wheel arch.
I'm going to order a few of these strips, can you tell me which strip you used for which area? (Such as Strip Large D front door?)

I'll take pictures of my trunk area today, but I don't have a hybrid battery so that might be why I have those gaps.

In the photos, where the orange circles are, is where the gaps were.

Second windscreen? Damn! Sorry to hear that. Hopefully, there won't need to be a third!

I watched them replacing the windscreen. There is little to none insulation between the roof and linings. Also the "paravan", the big plastic piece underneath the windshield and hood is completely un isolated.
