allow cyborgs some sort of shuttle safety mechanism

[Grek]

If it were ruled something had to be done just make borgs buckable in chairs (BUT) Borgs cannot unbuckle themselves.

That's a terrible idea. Why would you make it so that borgs can buckle themselves (or worse, be buckled by others) but not unbuckle? That's just pointless fuckery.

Just let borgs use the standard buckle and unbuckle mechanic for chairs.
