I don't see that anything in improvement suggestions section is going to take away time from LFS development to direction devs has chosen, they follow their route in their schedule that is basic principle of how LFS is being developed, if devs see what they like they may add it to list, but certainly never it is going to cause development direction or speed to change, besides I remember reading quite long time ago that Scawen did had quite complete list of features for LFS, it was something among lines of suggested features list is quite full already or something like that, but it was really long time ago so I believe only small details and such are those that really affect at the moment.
That is why I have started to think that there could be different products like:
-LFS learning edition, now contains traffic rule sets of most countries
-LFS Drifters touge, feel the exitement of sideways action in most challenging touge courses evah
-LFS Mod, create your own cars and tracks, enjoy world of customization.
-LFS Online racing simulator, the original LFS, the one and only the best online racing game there is, comes with LFS World stats, you won't find them elsewhere
Naturally such developments should be made after this first product is ready.
That would be how to make quite some money out from it but I really can't say if that is what devs ever would enjoy of doing and if it is not what they would enjoy what they would like then it is not going to happen either as we know LFS is game made without strict schedules etc. it is why it goes further in simulating as there is passion in making, will to create something that creator enjoys.
But for threads, well I would say that there could be some filter when you hit post if there is drift or freeroam in title it would not make a post but direct you to search function and uses title as search word
