>If the system starts to brake every time it thinks it might need to, it will happen all the time. It might see false positives like this all the time and that's why it doesn't act on them right away.

if your car always sees empty space ahead as non-empty space, you probably shouldn't let the car on the road until you fix that. Once you fixed that, if the car sees that the space ahead is non-empty, even it can't classify it, it should slow down well before and warn the driver and continue with the braking if the driver is asleep/watching youtube. It is AZ, there is no rain nor snowflakes falling which would mislead the lidar. An object ahead - slow down and stop if you can't navigate it.

Presenting it as the AI-hard issue of misclassification is just an attention misdirection from and a whitewhashing/laundering of the foundational issue of knowingly letting car on the road with missing basic safety level of "don't hit objects in front of the car". Similar to the Boeing blaming 737 MAX crashes on the failed sensor.
