So, what you are saying is that a taxi that came with the carseat installed (by sometime who does a lot of that and has liability for doing it wrong) is actually safer than your own car. I mean, maybe not YOUR car, but on average, safer.
I take your point about small children being filthy, though.
Fair point. And a lot of the cost of a driverless car will be software or infrastructure, so probably not a large unit price per sold vehicle.
