Perhaps the media machine chose not to show the laser scanning process because it doesnt *look* like as much effort is going into it to the layman.
You said you have never heard from an official source that T10 use laser scanning, I gave you an official T10 press video where they state that they used laser scanning combined with other methods, then you state that T10 dont actually know the right terminalogy for the technique and technology they are using just because they dont specifically show the laser scanning happening in the video and chose to show a more labor intensive method that was also used....pffft some people.
Sorry I mean reading about the process like I did with GT5:

I'm sure they have mistaken the "3D scan" process with "Laser Scan", all the media sites that published the Veyron vid thought they were doing a laser scan. The polygon meshes shown in the dev screens are typical from a manual scan process, not a super detailed laser scan, also was the tape grid put over all the parts in the Veyron. If I recall correctly they outsourced the 3D scan work to a different company is not like T10 representatives are experts in the matter.
About the different methods:
"The red Ford GT showcased in 'Forza Motorsport 4' demos was created from a mix of reference photos, 3-D CAD data, 3-D laser scans and, of course, test drives."
"vehicles get an extra degree of analysis: For the upcoming "Forza" title, developers took 3-D laser scans of select cars, including the Bugatti Veyron."

Nothing about any other 3D scan process except "laser" that is wrong for that car, the only one seen scanned.
Perhaps things are becoming different for FM4 who knows, I hope to see more information on their 3D scanned process. Things like pin accurate interior textures, smaller exterior details like light glass writting reliefs and accurate panels separation/placement are some of the details that you could expect with the laser help.
Edit: I found this interview from FM3 that confirms that they have mistaken the name process and outsourced the scan work. That explains all.

It's a pretty rare car, it's kind of hard to get your hands on it. But we found one through Bugatti in San Diego, somewhere in southern California. And we had this group named Acme that go in and they laser scan the cars. So the process is they go in and they put tape along the major creases and the major seams of the car and they basically outline all the really nice rounded shapes. And then they use the laser to actually scan those lines directly into a CAD drawing.
It allows them to get incredible level of detail on how they're scanning. And we also take thousands of photos of the car. We didn't drive it ourselves. We did talk to some guys that drove it in our reviewer community and they told us sort of how it drives and what have you.

We've got a very strong partnership with Ferrari so they give us all sorts of drawings. Again, that cuts the time down but the kind of time I'm talking about, I think would be the next generation of laser scanning. It's basically what we don't have yet.
I think what we need is, I don't know – that's what I mean about if we had the answer, we'd be targeting it already. That's what I mean about three to five years away. We just don't have the technology.
