There are other Simulations that ModTools offer. They have great graphics, great sound, infinite number of cars and tracks ..... and these simulations also have unfriendly and insulting users. The whole thing has less to do with the development than with the people themselves. Some just love to be in a bad mood and distribute their sweets.
Scawen once said something like:
"Lfs does not make your life better". And he is right. Especially with people who only want to look for mistakes from others. Seek your own mistakes, that makes your life better. xD
