An update on the autonomous self driving Uber Volvo XC-90 involved in the pedestrian fatality. It is being reported that Uber disabled the Intel Mobileye collision avoidance sensor that is factory fitted in Volvo XC90. Intel have ran the dashcam footage of the accident through the Mobileye system and said that even with the dark footage it would have detected the pedestrian a second before the incident.
