They say "go back to NFS" because NFS is the symbol of car-tuning (as in neons, NO2, audio etc.). If somebody would have asked for RPG elements, they'd tell you to "go back to WoW". That's all. The whole thing is about gaming stereotypes.
And why people don't rather say "unfortunately, there is no such option in LFS" instead? Because it's easier to be an **** on the internet. They wouldn't tell you the same thing eye-to-eye, because they would be affraid of getting their buttcheeks kicked. And it's also a means of ventilating their frustration with people, who cannot use the search button and ask for the same thing over and over.
And one last thing: everybody should learn to use words like "never, always, everybody, nobody" more wisely and with caution, as those are very strong words.
Now if you'll excuse me, I'm going to have some cop chases in my Murcielago. Gotta try my new exhaust pipe extension.
