May 8, 2018—Uber on Monday said it has retained a former top U.S. transportation official to advise it on safety after a fatal self-driving crash in March, reported Reuters.

Uber declined to comment on a technology website's report that a software flaw was responsible for the accident, according to the report.

The Information reported that the car's sensors detected a pedestrian but the car's software decided the car did not need to react right away.
