Cruise knew that its self-driving cars had been struggling to recognise children but kept its vehicles on the road anyway.

According to internal safety assessment documents obtained by The Intercept, Cruise was concerned that its vehicles might drive too fast at crosswalks or near a child moving abruptly into the street. 

The materials also indicate Cruise lacks data around scenarios such as kids suddenly separating from their accompanying adult, falling down, riding bicycles or wearing costumes. 

The materials also revealed that Cruise lacked high-precision machine learning software that would automatically detect child-shaped objects around the car and manoeuvre accordingly, and was relying on human beings to manually identify children encountered by AVs where its software could not do so automatically. 

Cruise responded that its vehicles had had 'no on-road collisions with children'.
