Another neat thing is that you and the people you are racing against all send the signal of what they are doing to the host and in turn the host sends it to each player. Between recieving signals your computer has to "asume" where the other cars are based on the previous information. When the cars "jump" cuz your machine asumed wrong its what we call "lag" Sometimes it makes for some neat pics though. As is evident by this incident at Daytona. Check out where the 98 (yellow) car lands.
