remember FH1 where you could follow your teammates around in follow-cam when dead? that's even more unrealistic and silly (but I still kind of miss it).
You can still do that. Unselect your spawn point (or else you will only follow them for a few seconds before you respawn), hit the X in the upper right corner of the spawn interface and hit "C" (or whatever your cycle camera button is). You follow them around until they die (in which case you begin following that player again once he respawns), until you hit "C" again (in which case you start following a different player), or until you respawn.
It doesn't have any use, because people who are alive can't see anything people who are dead type, and I think your voice is muted in BF2's VoIP while you're dead as well (plus, because the camera stays directly behind the player, you couldn't see anyone sneaking up on him or anything, even if the VoIP wasn't muted).
I normally only use this during WaW matches where I'm waiting for my Squad Leader to drive somewhere so we can squad bomb it. It beats staring at the Spawn Map for several minutes, at least. (And, because we use Teamspeak during battles instead of the BF2 VoIP, I can comment on the SL's bad driving.
)
