A: what US rate would have been if it had declined by same percent as British rate
B: what US fatalities would have been for US vehicle fleet if vehicle rate had been as in column A
C: the number of US fatalities prevented if US rate had declined in step with British rate
* If US rate changes had matched those in GB, 15,670 fewer Americans would have been killed in 2002.
In 2002, US fatalities would have been 27,145 rather than the observed 42,815 .
