So, in some sense, what this is suggesting is that it's not just that people are setting up their car seats wrong, which is putting children at risk. It's just that, fundamentally, the car seats aren't doing much.
Dit suggereert dus in zekere zin dat het niet de mensen zijn die hun autostoeltjes verkeerd installeren, waardoor kinderen in gevaar zijn. Fundamenteel halen autozitjes niet veel uit.
