Despite the high cost, the NHTSA predicts the rule will save only about 25 to 31 lives in 2025, mainly because it will do no good until most cars have it. Yet even by 2060, when virtually all cars would have it, NHTSA predicts it will save only about 1,000 to 1,365 lives per year.

Yet advancements in cell phones, wifi, and other technologies could do the same thing better for less money.
