On the one hand, I do worry about the effects of “safetyism”. On the other, I feel like car safety is not the particular place I want to address that issue. While they seem mundane because they’re so commonplace, cars are one of the most dangerous things in our society today. If it potentially saves a life? I am in favor of the tank like seats. I don’t think they’re embarrassing for kids because all their peers are in them too.
I do agree with this line of thinking in many other areas though. It’s hard as parent when you want to protect your kids, but teaching them resiliency and problem solving is also important, to an extent that is appropriate for the context they’re growing up in. (Kids growing up on the frontier 150 years ago obviously had a different experience than suburban kids in 2023, and that is true any way you slice it. But resiliency and independence can still be taught to a degree that’s appropriate to the current time and place.)
Anyways. Getting back on topic… if you’re a person who chooses to use the “big” seats… they’re a lot to travel with. Not impossible, but a big ol hassle for sure.
