Air bags only deploy when the crunch sensors (front ones are typically on or behind the front frame rail or metal bumper (for cars with plastic up front)) are activated. Or also when the car suddenly decelerates. There are advanced sensors typically mounted in the passenger compartment that detect a vehicles forward g's, lateral g's, and the tilt of the body. This data is sent to the SRS computer to help determine what the car is doing. If the sensors say the vehicle is cruising at 70MPH, then is suddenly going 0, the air bags will deploy. If you combine more crash sensors for side and rear, more or other air bags (such as side curtain or seat mounted ones) can be deployed to better protect the occupants based on impact speed and direction. Air bags are intended to prevent your torso and head from impacting with the steering wheel, just as head rests are there so your neck doesn't wrap around the seat back. However, if an air bag were to go off for you bumping into the car in front of you while parking at Wal-Mart, they would do more damage than good. Air bags deploy at amazing speed and slam into your face causing rashes and bruises. Also, the gas used to inflate them can asphexiate you.
But yes, the dashboard pieces, along with whatever crap is laying on your console or in your hand, will contine to travel forward (away from you) when the truck stops.
Air bags have become progressively smarter due to problems encountered in their existence. The earlier air bags were most likely not so smart. As a side note, air bags actually existed since the early 1970's but GM fought any and all attempts to put them on cars.

I've said before the 94-97 dashes were different and better than the ones that came after. I can't complain about my dash either. The only thing I found was crappy on my truck was a cheap water pump.
