General Motors’ Cruise updated all the software and claims the same mishap will not happen again.
Following a June crash in San Francisco that injured two people, General Motors’ startup unit Cruise LLC announced on Thursday that it has recalled and updated software in 80 self-driving vehicles. The National Highway Traffic Safety Administration (NHTSA) stated that the recalled software could cause the autonomous driving system to incorrectly predict another vehicle’s path or be insufficiently reactive to a road user’s sudden path change in certain circumstances, such as when making an unprotected left. This could result in a serious mishap, prompting the company to recall and update the software.
Cruise stated that the unusual scenario would not reoccur following the software update. It also disclosed that, following the June 3 crash in San Francisco, it temporarily prohibited its vehicles from making unprotected left turns and reduced the area of its vehicular operation. In a statement, the company stated that autonomous vehicles are even better equipped to prevent this singular, exceptional event. It also stated in a statement that all vehicles received software updates and that the recall has no impact or change to its current on-road operations.
Cruise said that the self-driving vehicle had to decide between two different risk scenarios and chose the one with the least potential for a severe collision at the time before the oncoming vehicle’s sudden change of direction. In rare circumstances, Cruise said the software caused the autonomous vehicle to hard brake while performing an unprotected left turn that it deemed necessary to avoid a severe front-end collision.
Following the July 6 software update, Cruise stated that it had gradually reintroduced unprotected left turns, which refer to turning left at an intersection with a solid green light that directs all traffic rather than a designated green arrow just for turning vehicles. It also stated that the incident was unusual.
