Potentially but radar is still better to eliminate these false positives.
Also the existing HW3 cameras are not very good---human eyes in fovea are significantly better, with better autofocus and color perception, and less glare sensitivity.
Straight vertically undulating roads with no cars, like mirages, also trigger the errors. The resolution isn't good enough far down the road, where humans can see there's nothing there, and use their brains knowing that there is no hidden car in the dip stopped.
And this is why even ML heavy auto driving companies still want additional sensors. HW4 has better cameras too. But more bits in the cameras means much higher compute burden and needs more expensive chips and higher power consumption.
