Nice, you just outed yourself as being completely clueless. There exist many good sensor fusion techniques for summing the output of disagreeing sensors.

Sounds like bad designs. If you can get rid of something to reduce complexity you absolutely should.

Except when getting rid of something results in a non-working system. Reduced complexity doesn't work as evidenced by Tesla's inability to have a single driverless mile after nearly a decade of development.

Did you forget why the 737 max had 2 crashs ? The alert of the difference between 2 sensors didn't work / wasn't there. So the system was relying on 1 sensor.
