I don't know if this has been brought up yet but if it has oh well repition is not always a bad thing.

I loved my car in Fallout 2 i thought having a car was badass and as far as like a transportation thing i think it would be cool to have one in Fallout New Vegas, but i don't really know how it would work considering the fast travel in Fallout 1 and 2 were a lot different then Fallout 3's and New Vegas' fast travel is probably going to be like FO3

It has already been confirmed that there will be no player operated vehicles, and you are right, it has already been discussed in (many) other threads. http://www.gamesas.com/index.php?/topic/1093148-vehicles-player-operateddune-buggygyro-chopper/. Please use one of the other topics.
