Edit 1: Sorry I was wrong. The world scale adjustment in Flyinside option applies BOTH to the cockpit AND the outside world. I increase the cockpit size to maximum and the road beneath me becomes very broad too. This is fantastic! I am very happy. Thank you Dan for the brilliant work!
Edit 2: There are still problems. When I increase the cockpit size to maximum, the nearest cars, buildings, etc will look like normal size, but the cockpit will become absurdly big. So the cockpit is still out of portion with the nearest surroundings.

Flyinside is absolutely incredible, but I find the new dimension it brings to FSX may also foreground the intrinsic problem of the non-VR applications. I mean the world scale problem. I do feel the landscape in VR mode looks smaller than in real life. This is more obvious in photoreal sceneries because there are real objects for reference. I attached a picture of the Bell 206 landing in the highway of Aosta. I made the scenery with 50cm aerial photos from Bing Map. As you can see the lane looks unrealisticly narrow. It is almost as narrow as the helicopter, which can't be possible. But I really don't know whether this is the problem of FSX, or Flyinside. Or is there any way to change the world scale? Yes I know there is an option in the setup panel, but it is for the adjustment of the cockpit, not the outer world. Any ideas?
