Probably for the same reason that the engines are on these skinny little pylons and the Saucer is connected to the main hull by another skinny little pylon.
They did have a "battle bridge" in the STNG Enterprise, that was presumably in some sort of a "safer" location (don't know if it was ever specified). But that was quickly forgotten as the idea of having to eject the saucer section any time there was danger, was silly, consumed too much money for SFX and time in the episode.
In other words it's just one of those things you have forget about and move on because "that's just how things are and there's no good reason for it." There's so many far sillier and stupid things in ST that make even less sense that this doesn't even rate on the scale.
Besides given how the warp cores seem to explode if looked at funny in the NG era shows, the location of the bridge is generally the least of their concerns.
