The miracle of life happened in the passenger seat of a couple's car in Houston ... and they recorded the whole shocking birth.
This video purportedly shows the woman in labor -- on her way to the hospital, we hope -- screaming as her water breaks. Just a few minutes later a 10 POUND baby drops out of her uterus.
We have no idea if this is the real deal, but man ... it's entertaining to watch! Serious edge of her seat drama.
Kudos to the driver for remaining so freakin' calm (too calm, really). Mom did aight too.
