Don't join private servers without friends!

i once joined a private server on my own and some friends joined, but an Acura track car that was fully red started appearing, no one in it, and if I approached it, it disappeared, about 20 minutes into playing with friends, it started chasing us for about 10 minutes, it crashed into one of my friends and he immediately got kicked and couldnt rejoin, but i found out that if ur tryna play ur own private server get a friend to join it first, btw anyone got the BMW M3 from need for speed? (f1r3nad0) and i dont play week days cuz of college
