That's not really a helpful comparison. The safety considerations on a track are very different than on the road.
Safety devices on modern vehicles aren't independent variables -- they are designed to work together, and they're designed for particular risk cases.
Street cars have some design criteria that isn't the case for some of the safety systems on track cars: for example, the safety systems in a passenger vehicle are designed to work without a helmet or a HANS, which is often not the case with track cars.
If you are not wearing a helmet and a HANS, you are safer wrecking a car with an airbag and a 3 point belt than a cage and a harness, where you'll end up with a concussion and a basel fracture.
Also, crashes on a racetrack are overwhelmingly with barriers or with vehicles with similar vectors of motion. On the road, impacts at 90 or 180 degrees with vehicles of varying masses are much more common, and then, mass becomes a significant factor in the forces imparted upon occupants.
