"The DoT said that mandating V2V communications could add $300 to the cost of making each vehicle, but that it would save up to $71 billion as a result of lowering the number of vehicle collisions."
So is that a savings or not? How many billions per year is $300/vehicle, or how much per vehicle is $71 billion? The figures sound impressive but they're in completely different frames of reference, so can't be directly compared.
Also, dollar figures are fine, but presumably one of the costs of collisions is lives lost. How many lives saved are we talking about? How many permanent disabilities?
For that matter, there may be other costs associated with the addition of the new system, some of which have been enumerated by my fellow commenters. Who will be paying for attack mitigation? How many people will be late to important meetings because of some script kiddies?
The mind boggles!
