and
drum roll please. The results are in.
My analysis and hypothesis that the solution to annoying wind and road noise lies with the A-Pillar has been proven true.
1. Wind noise has literally disappeared.
2. Front road noise has been calmed down to a feedback level. No more of the annoying gritty sharp road noise.
The solution is as shown below in the pictures before and after.
Before:
As you can see the front fender that meets the A-Pillar is completely barr as well as disconnected from the A-pillar. This was the source of the wind noise from the top coming into this space.
The road noise from the tires was also making its way to this zone which interestingly is also where the midrange speaker is located on the door. That is where our ears are naturally focused and hence the annoyance.

After:
The solution is to fill that gap with a sound isolating barrIer. The easiest and lightweight way was once again relying on the PE foam (uxcell or siless), cutting it to this shape and sliding it in there. Here is how it would look once in place
My Inspiration to this solution is my Mercedes. A picture of that is also found below:
