No, you're not getting my point.
In such an accident you would have sufferent blunt force trauma, which is very common due to many reasons, traffic accidents, falling off ladders, running into poles while messing with your phone and what not.
Same goes for things like cuts - it doesn't usually matter that much if you cut yourself with a kitchen knife, screwdriver, on the edge of a table, by a sharp piece of glass or whatever.
These are very common injuries and many people will judge if they appear severe enough to warrant a medical exam.
But in case your airbag randomly went off (without a collission, electrical malfunction or something) and you have no obvious injuries i can imagine going to a car forum to ask about how that could happen, and find someone there advising to seek medical care for potential internal injury as those things go off with quite a bang.
The thing is that people on here find these questions stupid since we have some knowledge of power levels and risk. Someone that just buys a laser as a novelty toy thing may have no clue. Many of us could guesstimate that a reflection from a normal house window from a 500 mW laser is actually quite dangerous (as it would be 20 mW ish), but someone without any knowledge of this could easily thing that the reflection could not be that powerful since it's a window, not a mirror.
