Designing Safety Systems? Keep Air Bag History in Mind

Safety By Design

No, aliens have not landed! The image is a Pedestrian Detection Systems indicator symbol. It is associated with a new system now being deployed. What looks for all the world like energy beams emanating from a humanoid’s hands are actually meant to be lane lines the human(oid) is standing in.

But this article is not about the warning light, rather about new auto safety systems in general. We retweeted this item from Retro Report in November. It is a video that traces the history of safety systems in cars, particularly that of air bags. We hope that everyone currently working on new automotive safety systems is well versed in this history. Air bags have saved countless thousands of lives since their introduction in the 1970s, but many others died while the industry worked out a few flaws in their first iterations.

Soon after their adoption, the industry discovered that the force of an air bag deployment could and did kill children and small adults. No one thought of this in advance of their use. The result is that we now host young children in the back seats and sensors keep passenger side airbags turned off until enough weight is detected in the passenger seat. A light like the one in the image will appear somewhere on the dashboard.

Air Bag Recalls

Currently a massive recall continues because of flawed air bag inflators. Shrapnel from inflators have killed drivers. Already recalls have been issued to address auto baking systems that were randomly deploying when a collision was not imminent. No one has been hurt or killed by these systems, at least not yet. And now we have pedestrian detection systems being deployed.

New technologies always result in problems before they are truly effective. Anyone who’s ever owned a computer can attest to that. And of course, computers and software are at the heart of today’s safety trends.

Ultimately the plan is for cars to drive themselves, and some can in limited settings, and we’ve already seen drivers do absolutely moronic things with their cars while on autopilot: setting excessive speeds and leaving the driver’s seat completely.

There are very, very smart people working on these systems, but what might not be thought of in advance of deployment is what will come back to haunt us all. We hope that they keep the troubles encountered making air bags work, and keeping them working, in the front of their minds at all times.
