Because the trade off is extremely rare. Humans became bipedal to travel great distances, other animals either can do that on four legs, or were evolved to live in trees. Our evolutionary history is quite unique, we are descended from climbers/tree dwellers, and then went back to land.

I’m a PhD candidate in biomedical sciences, but people I’ve met in human evolutionary biology feel extremely confident the switch to bipedalism was about energetics of long distance travel. May be due to that too but it’s a walking thing!
