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!
