How many automobiles are completely incompatible with car seats?
I've read the laws; they're very in line with maximizing 'kiddo safety'.
Compact extended cab pickup trucks with side-facing jump seats in the extended portion. More than a few were produced and are still on the road. I owned one until an elderly woman decided I ought to drive something different a few years back.
1. The side-facing jump seats are incompatible with any of the kiddo safety seats I encountered, physically/design-wise. Specifically said in the instructions that the seats were to be mounted fore/aft.
2. I finally did manage to mount two of them (side-facing). Not pretty, but secure in the way an over-engineer would do things.
3. Funny thing, though. When the kids sat in the jump seats with no safety seat, three sides were surrounded by firm padding and one side (facing the other side of the cab) was open. Like the jump seats were designed to transport small humans in as safe a manner as possible. When the kids were ensconced in the "better protection than a race car driver" safety seat, that
raised them such that their heads were now in line with a rigid metal strip. Now,
instead of encountering the firm padding all around (and relatively close, sort of like school bus seats are supposed to work), their skulls would be crushed by the metal strip in a fore/aft collision. Hoo-*expletive deleted*ing-ray for child safety seat laws. Thank you, policritters and dumbass activists for putting my children at greater risk of traumatic brain injury. I first went to making the kids wear styrofoam bicycle helmets and then rigid skater helmets to counteract the unintended consequences of crapulent doo-gooders.
The law is an ass promulgated by dumbasses who did not take into account that
their law was incompatible with literally millions of motor vehicles sold and still on the road in the last few decades.
