Volvo XC90s are supposed to come with a pedestrian detection system. If it was disabled by Uber, Uber is as fault. If it was active, and failed, it may be Volvo’s fault.
Edit: found these conditions on Volvo’s website:
The following conditions apply:
In order to detect a pedestrian, the system must have a full view of the person’s entire body and the person must be at least 32 in.(80 cm) tall.
The system cannot detect a pedestrian carrying a large object.
The camera’s capacity to see a pedestrian at dawn or dusk is limited, much as it is for the human eye.
The camera’s function is deactivated and will not detect a pedestrian in darkness or in tunnels, even if there is street lighting in the area.
WARNING
Pedestrian and Cyclist Detection with Full Auto Brake is designed to be a supplementary driving aid. It is not, however, intended to replace the driver’s attention and judgement. The driver is always responsible for operating the vehicle in a safe manner.
The system cannot detect all pedestrians in all situations, such as in darkness/at night and cannot detect partially hidden pedestrians, people who are less than approx. 32 in. (80 cm) tall, or people wearing clothing that obscures the contours of their bodies.
