If the vehicle rolls, the module triggers release of a series of curtain airbags from the headliner trim in as little as 130 milliseconds. They have fixed attachment points front and rear to help prevent passengers from being tossed out of the vehicle during rollovers. This makes us nervous. We've heard this kind of talk before. The argument goes something like this.
People are too stupid to put on their seatbelts.
They're getting themselves killed. We'll develop a foolproof system that will save them. The problem with foolproof plans is that they aren't foolproof. The original airbag design deployed too forcefully, taking dozens of lives. Now, we are not advocating sacrificing numbskull drivers and passengers to the automotive gods.
