I had a Mazda 3 hatchback, fun little car with stick shift, when our second child arrived. It was not possible to fit in a second rear-facing car seat behind driver AND have the driver seat be in any acceptable position for me or my wife, there was just no space left in front. We researched the seats and ultimately it was easier to get a bigger car than mess with it, so we got a Volvo XC70 that had plenty of space. Once the kids could face forward, the typical Graco style seats were too wide and the middle rear passenger seat was not usable, so we invested into 2 narrow-profile seats that left the middle seat more useful. I can't remember the brand anymore, but it took a lot of research to find the narrow ones and they weren't cheap.

And none of this have contributed to us not wanting more than 2 children. That wasn't going to happen regardless of any car seats. People not wanting to have more than a 1 or 2 kids has so many other, more important reasons, I very much doubt that car seat size has much to do with it.

You're not really arguing against the paper; the study showed a lower birth probability of only 0.73% in places with car seat laws. That suggests that yes, sometimes it does deter parents from having a third kid, but most of the time it does not. And the paper doesn't say that the third car seat issue is the only consideration parents might use to dissuade them from a third child.

Yes and no. It is a bunch of little and big things that add up to that decision.

It is interesting to see how much the car seat issue adds to the decision making.
