So let's do this math:

Total light duty vehicles sold in the US (2002):
16,817,500

Price per vehicle of this system:
$70

Total price of installing this system for one year:

$1,177,225,000

Total lives saved:

120

Price per life saved:

$9,810,208.33

So you and I are going to be paying almost $10M per life saved! That's a VERY expensive solution to stupidity!
