Every time I read about Gerber I wonder who the target market is. Then I remember that I'm a childless adult with a pantry full of food and lots of takeout menus on hand. And then I realize that Gerber is made by and for old, married, child-bearing couples with who live in the Midwest.
Obviously those with young children specifically are in a different position and that's likely to be hard to address. You'll have a particular pram/stroller you use and specific snacks. You're more likely to be tied to your car if you don't want to be packing and unpacking each time. I get it - I have a car with a car seat for a 2yo. But there are also loads of times I'd use an Uber service alone or with my partner or even with a child if it were prevalent in my city.
But transporting young children is a specific use case, and it's a very common one where something like Uber isn't really an attractive or viable substitute for your own car given the bulky support paraphenelia required, often by law (car seats, strollers etc.)
You will be able to give your full attention to your children instead of having them distract you from the road. In the future it might seem downright irresponsible to drive your children yourself. Sure you'll drive for fun sometimes, but not with the kids in the back.
Parents do plenty of horribly "unsafe" things with their kids, but the point is _they_ do them -- they aren't going to pass the responsibility for their children's lives on to a computer willingly. Heck, I've known people who refused to take their children on driverless trains, they sure won't put them into a driverless car.
No, you didn't actually say anything like that. But your post is pretty heavy with dismissal, as opposed to just saying "I don't think that this would work for my situation because A, B, C...". I doubt that something like this can accommodate even close to most people's lifestyle and needs, but there is no need for this "pff, only those privileged young people would find this useful" crap.
