If witnessing a birth in a driverless taxi wasn’t on your radar today, you’re not alone. Yet, that’s precisely what unfolded in a self-driving Waymo car in—where else?—San Francisco. A hearty congratulations to the new parents! At least this Waymo event steers clear of any traffic violations, although… let’s just leave that thought there.

Fast forward to the future: Once this child grows up, they’ll have an extraordinary tale to share. Interestingly, the report doesn’t specify the baby’s gender, perhaps honoring San Francisco’s progressive approach to gender identity.

Describing this as an unusual experience for a passenger in a self-driving car might be an understatement. Reflecting on the outcome and my personal experiences with childbirth (including adopting one of my children), it’s probably wise that Waymo isn’t delving into the nitty-gritty details. Some moments are best left to the imagination.

Now, here’s where it gets intriguing:

The new mother has undoubtedly faced a unique and likely challenging situation. It’s understandable she isn’t granting interviews—she’s navigating enough right now. There’s a popular anecdote, often credited to Carol Burnett, about the childbirth experience: “Take your lower lip and pull it over your head.” This new mother accomplished that feat in a self-driving car. With that and a newborn to care for, she certainly has her hands full.

The mother was on her way to the University of California, San Francisco medical center Monday when she delivered inside the robotaxi, said a Waymo spokesperson in a statement Wednesday. The company said its rider support team detected “unusual activity” inside the vehicle and called to check on the rider as well as alert 911.

Unusual activity, at least for a passenger in a self-driving Waymo vehicle, may be something of an understatement. Given what we already know about the outcome of the event, and based on my own experience having been present at the births of three children (one of ours is adopted), I can say that it’s probably for the best that Waymo isn’t discussing this in detail. Some things are better left unsaid.

Here’s the interesting bit:

The taxi and its passengers arrived safely at the hospital ahead of emergency services. Jess Berthold, a UCSF spokesperson, confirmed the mother and child were brought to the hospital. She said the mother was not available for interviews.

The mother has been through a rather unusual and certainly unsettling experience, and we can’t blame her for not granting interviews; she’s got enough to deal with as it is. There’s an apocryphal quote generally attributed to Carol Burnett, who reportedly said that one could understand what it felt like to give birth thusly: “Take your lower lip – and pull it over your head.” This new mother did all this in a robo-taxi. With that, and a new baby, she’s got enough to process.

What’s remarkable is that the Waymo car and the company’s rider support team were clearly up to the task and got her to the hospital in good order, even beating emergency responders to the scene. But, according to the parent company, Alphabet, this little one wasn’t the first baby born in a Waymo vehicle, they apparently have some experience in these things.
