The automotive safety bill progressing through Congress promises to make automobiles much safer for consumers, but in the process, they will also become more expensive. The reason for this is that the National Highway Transportation Safety Administration (NHTSA) hopes to equip all vehicles with ‘black boxes’ similar to those installed in aircraft.

Some estimates say that more than half of the new cars and trucks on the market today are already equipped with these event data recorders. The device, a small computer mounted in the passenger compartment, continuously records and deletes the most-recent few seconds of data about the vehicles speed, acceleration and deceleration, and other performance factors. They are also part of the airbag control unit, which uses vehicle data to determine when to deploy airbags.

The problem with the already existing computers is that they are not durable enough to withstand a crash. In order to do this, they must be made waterproof and fireproof, adding more bulk and complexity which will lead to a total new design of the system. This could increase the price tag of a vehicle by $4,000 to $5,000 more.

While the NHTSA advertises these ‘black boxes’ as a good thing for consumers, it’s an even bigger business opportunity for the suppliers of the technology. If the bill passes, the regulations would take effect beginning in the 2015 model year, but the specifications that NHTSA will mandate for the ‘black boxes’ have not been determined yet.
