It's really interesting to me that whenever anyone talks about homeschooling children the point that is always raised by someone is that if children never leave the home then how will they learn to socialize with children their own age.
Similarly, whenever people talk about skipping grades for exceptionally bright children someone always brings up socialization.
Yet here we see many people talk about how leaving children unsupervised in a self driven bus is a recipe for disaster. Which seems to suggest that children socializing with their own age is a detriment to both society and the children themselves.
I'm sure nobody is using data to come up with these conclusions, but I find it interesting that the expectation is that kids socializing with kids is both the most important thing AND the worst possible thing.
