That's exactly how a lot of commercial aircraft systems work, they have three, if two agree and one disagree then that one is ignored. But it is more complicated than that when you're talking about algorithms and complex systems. If you had three of the same exact system, they'd likely all make the same mistake and thus you'd gain no safety improvement (except actual malfunctions, not logical limitations). I would like to see auto-braking taken out of autopilot completely, so if autopilot drives you into a wall at least the brakes slow you.

I'm not an expert...but it seems like for airplanes there are standards that manufacturers need to abide by for avoidance systems...which would mean testing and certification by an independent association before it's deployed. With manufacturers doing OTA updates...there's really no guarantee it's been tested...you'd have to trust your life to the QA process of each manufacturer. Not only the one of the car you're driving...but the car next to you!

This has been mentioned a lot of times lately (the auto-braking). When you think about it, you realize there are a million moments during normal driving where you have an obstacle ahead. Other cars, lane dividers like these that you might _have_ to pass by closely, or at least will have your car pointed at it for a few seconds, making tight curves on a walled road, high curbs, buildings that are on the edge of the road, etc. It's not that simple, and I bet a lot of this is already taken into account by the software.

  My understanding is that auto-braking during autonomous driving doesn’t normally react to stationary objects like barriers. Otherwise it would brake for things like cardboard boxes, plastic bags, and other debris that often makes its way onto the road. But rather, autonomous driving AI puts a lot of trust into its lane guidance.

    Will it run over accident victim, animal, or slow down and ask the human?

    In what world would you not want your car to brake for a cardboard box? You don’t know what is inside. It could be empty, or could be full of nails. Or a cat. Regardless, it should be trivial have a different behavior for a moving object that enters the road versus a rigid object that has not been observed moving.

      Sometimes it's just a piece of paper or something similarly harmless that happens to be positioned on the road in such a way that it appears to be an obstacle.

        If a system can't reliably differentiate between a flat object lying on the road, an object fluttering rapidly in the air, and a stationary object that is protruding from the road, it has no right to be in control of a car.

As far as I know things like the space shuttle had 3 different guidance computers developed by 3 independent teams. They were given the same requirements and came up with the hardware and software independently.
