all the talk about the sureride has got me thinking, how is it determined which top slots are safe to use in which directions? With the sr for example, in the US you can use the bottom 3 for RF, the 4th from bottom either direction, and the rest of the higher slots (sorry don't remember how many) for ff only, but IIRC in Canada only the bottom 3 slots can be used RF. Does anyone know how they determine that? I know US and CA standards are different, but what is is about the design of the seat that makes it safe to only use certain slots certain directions? Is it the way the slots are reinforced? Is it how it performs in crash tests, do they say " the bottom 4 slots held up to our expectations rfing but the rest didn't so only those are ok for rf?"
