Since this forum seems to be dedicated to potentially interesting ideas that will not likely be implemented, I'd like to add mine.

I want GPS log importing in LFS. I want to find a fun road, drive it while logging the GPS information, import this log into LFS, and have LFS create some terrain and scenery that follows the road. Yes, artificial scenery is never all that exciting, but just think of all those roads you've ever wanted to drive fast. Me, I'd take this over Nuerburgring.

So basically you want to be able to make your own track.

Been discussed many times, but either way, a simple GPS track won't get you what you need, it will just get you the turns and maybe at best some altitude, but it won't be accurate to your drive at all.
