I connect to a server, join the race and other players can't see me, they can't even see my name and other stuff over car. When this happens i can run thru them and nothing happens to them, only i am getting damage. Connection is fine and ping is not more than 60-80 for eu servers. And this kind of problem happens only in LFS.

Surf the linked topic for more clues. For example:

...Check your firewall if not blocking your ports TCP/UDP of LFS.

Those guys there solved the problem.
