How safe is it? Compared to other 1976 cars very very good. Compared to a modern car? Not that good. As other noted, in a crash your head is going to hit the steering wheel. 1985 models did get seatbelt pretensioners. I would not describe it as unsafe. Check out copart.com for real crash pictures.... you'll see the old design holds up well.
