Not sure if this has been said before in the past years but....
Say for a race that only uses 90% of fuel for a certain car, putting it "pit stop required" for 1 stop (2 stints) isn't enough 'fun' in terms of strategy. So, you have an option to change it accordingly as long as the number of stints does not exceed lap count, making the race much more interesting (both online and offline).
If you have never heard of them before, then on the main LFS website under the tab 'Additional Downloads' section there should be a Music addon pack for LFS. It consists of all of the 17 songs as I have mentioned above.
As for the virus thing, there is 100000% no virus. I have recently got a new awesome gaming pc, so there shouldn't be any traces of viruses.
On the track length select panel how about this: you press on the *laps and there's a selection of; laps, minutes, hours, km/miles and practice.
With the km/miles you go to options>game and you can choose either kilometers or miles.
My parent's computer(XP) speed on desktop is ok and the speed of the connection is fast but the whole game is so slowwww that i need to go to the bird's eye view mode to drive!
What can i do to make it faster?
Racesimcentral.com had been closed down because of an error along with a few other racing games. One of them is Generally. If you find LFS addicting then you would probably get addicted to this game. It's freeware and the size is only 1-2mbs.
The game has 31 tracks already in it and a track editor with it! You can also create your own sounds but the files must be wav. music files. For additional tools go to http://www.generally.com.ar/, you can find a car editor, main help file, options tool, track tool and savegame reader.
