Car seats are not required on planes because doing so would reduce the number of available seats, which would raise fares and cause more families to drive.
Rather than keeping your baby on your lap, you would need to strap the child into a seat beside you, which would raise your travel costs and overall fares.
Economists did the math:
For every child whose life might potentially be saved by being strapped into a car seat on an airplane, another 60 children would die in car accidents from opting to drive instead of flying because of costs.
Kind of amazing.
Math saves lives.
