But essentially, do something like this, which I don't know exactly how much it would cost to do, but there's no reason I could see why this should be much more expensive than a regular car seat.
Men i stort sett, gör något åt det här hållet, som jag inte vet exakt hur dyrt det skulle bli, men jag kan inte se varför det här skulle vara klart dyrare än ett standardsäte.
