That's a valid point. You should NEVER lock one that's loaded. It's unsafe. Empty it first.
Airbags CAUSE accidents. If it deploys from a minor bump, you're likely to smack something if you're still moving--it bruises your wrists, throws your hands off the wheel, and obscures your vision. Additionally, as it's unsafe to have an infant in the front seat with an airbag, you have to constantly reach over to the rear to deal with said infant, thus being distracted from driving. Or else risk having said infant smashed to jelly by said airbag.
I favor "airbag locks" myself, to prevent them going off by accident.
And I will never @^$% drive a car that has one. Even if I have to blow it off myself and epoxy the cover back over an empty slot. I wear seatbelts. Seatbelts work. As long as the user uses them.
Actually, you can draw a great parallel between airbags and trigger locks--both are attempts to bypass human stupidity. Both cause more trouble than they avoid.
Though I understand the Clinton's limo has dual airbags.
And my minigeeks climbed to the counter and accessed the kitchen knives at 18 months. This is why I keep them on a 6' shelf (The knives, not the kids. I just duct tape the kids). Junior geek (Eric Vatbrok Williamson
) is not quite three and still unsure of such things.
