Today, we get two normal fobs. I see the safety fob being part of the the standard equipment list for all new cars, much like any other piece of safety equipment because it lets both the driver, pedestrian and by-standers know there is an at-risk pedestrian in the area. One alternative is the ability to reprogram a standard fob into a safety fob. Issue three fobs with one configured as a safety fob.

I've bought fobs for the NHW11 and NHW20 along with a keyless development system to more fully understand the technology. Lesson's learned: (1) the fobs are microprocessor controlled, which is critical for vehicle operation but makes them unusually flexible; (2) the data rates are modest but easily decipherable and; the small 1x2 inch or smaller boards have very few parts, very cheap to produce. 

I don't underestimate the technical challenges of making a practical, universal safety fob but  seat belts and air bags had resistance and development challenges too. Sad to say, the language of the Stearns amendment all but rules this approach out. Otherwise, I and a few others would be pretty busy right now.

The owner has the option of either keeping for their own use, say a pre-school child or elderly family member, or letting the dealer donate to a local service organization.

The safety fob is tested by walking outside. The receiver operation is automatic and built-in to the vehicle. As for the horn bleep, testing would be needed but such testing should include more of a click versus even the muted bleep of the Volt. As newer vehicles come into the fleet, they would increase the population and because they are 'on demand,' even older vehicle drivers could hear the warning from the newer cars. In contrast, the constant noise generator becomes "the boy who cried wolf."
