Open face helmets typically offer wider field of view, and they're
lighter.  So no, depending on the details of the incident, full face
helmets are not necessarily safer.

Not if your head comes back to hit it in the same place, it might not
be.  Depends on the details of the incident.

No, not if the typical angle of attack to the wall is shallow.  Anything
crushable will tend to "catch" the car and throw it back, while cars
simply slide along the concrete while they dissipate energy.  Depends
on the nature of the crash.

Everything is a tradeoff.  Let the experts make the call.

Safety gear also certainly affects the sanctioning body.  Look all
these people beating up on Nascar for not being more proactive with
respect to safety -- don't you think this is all gonna hurt 'em where
it counts (in the wallet)?  They have a vested interest in preventing
injuries too, just like the sponsors, the teams, and the drivers.
