We're going to tell you what we see playing out in this video:
We reckon that's not the driver of the Hyundai Matrix's wife who he's stopped to flirt with in the middle of this rather tough looking neighbourhood. We think his suspicious wife has rigged the airbags in the car to deploy should they detect the perfume from another woman and that after saying their sweet goodbyes to each other the wife gets her revenge when what looks to be both the driver side and curtain airbags deploy for no apparent reason.
What this love triangle does provide us, the viewer, with is a good chuckle though.
Disclaimer: This is the only recorded case of a Hyundai Matrix airbag spontaneously deploying.
