Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident related to allowing drivers to play video games on Tesla cars while the vehicles are moving has happened again within the same organization. The incident involved a new feature in Tesla cars that allowed video games to be played on a large touch-screen while the vehicles were in motion. This feature was included in a software update released by Tesla over the summer, raising concerns about safety risks and distractions for drivers [122661]. The National Highway Traffic Safety Administration initiated an inquiry into this feature, highlighting the potential safety hazards posed by allowing games to be played while the car is in motion. Tesla's Autopilot system, which can operate the car autonomously, has also faced criticism for its lack of safeguards to ensure driver attention on the road, with several traffic deaths involving Tesla vehicles operating in Autopilot mode [122661]. (b) There is no specific information in the provided article indicating that a similar software failure incident has happened at other organizations or with their products and services.
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the article where the National Highway Traffic Safety Administration began looking into a new feature in Tesla cars that allowed drivers to play video games on a large touch-screen while the vehicles are moving. The concern was raised that the games could pose a safety risk by distracting drivers, indicating a design flaw in allowing such activities while the car is in motion [122661]. (b) The software failure incident related to the operation phase is evident in the same article where it is mentioned that the new games added in a software update by Tesla could be played by a driver or a passenger in full view of the driver, raising questions about safety and the potential for distracting drivers from the road. Despite warnings and prompts asking for confirmation that the person seeking to play the game is a passenger, there was nothing preventing drivers from starting a game while the car is in motion, highlighting an operational failure in ensuring safe usage of the system [122661].
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident related to the Tesla cars allowing drivers to play video games while the vehicles are moving can be categorized as within_system. This is because the failure, which could pose a safety risk by distracting drivers, originated from the software update released by Tesla that enabled the new feature of playing games while the car is in motion [122661]. The software update introduced the capability for drivers or passengers to play games on the touch-screen, raising concerns about distraction and potential safety hazards. The warning message displayed before starting the game indicates that the software itself allows for this behavior, indicating an internal system issue. (b) outside_system: The software failure incident can also be linked to contributing factors originating from outside the system. In this case, external factors such as regulatory concerns and safety agency inquiries play a role in highlighting the potential risks associated with the software update that enables playing games while driving. The National Highway Traffic Safety Administration expressed concerns about distraction-affected crashes and the safety risks posed by the new feature, indicating external scrutiny and pressure on the software system [122661]. The involvement of regulatory bodies and safety experts from outside the system influences the perception of the software failure incident.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident related to non-human actions in this case is the introduction of a new feature in Tesla cars that allows drivers to play video games on a large touch-screen while the vehicles are moving. This feature was included in a software update released by Tesla over the summer [122661]. (b) The software failure incident related to human actions in this case is the concern raised by auto experts that the video games feature in Tesla cars could pose a safety risk by distracting drivers. The National Highway Traffic Safety Administration has begun looking into this feature and is discussing it with the manufacturer, Tesla. Safety experts have also criticized Tesla's Autopilot system for not having enough safeguards to ensure drivers keep their hands on the steering wheel and eyes on the road, which has been linked to traffic deaths involving Tesla vehicles operating in Autopilot mode [122661].
Dimension (Hardware/Software) hardware, software (a) The software failure incident related to hardware can be seen in the article where the National Highway Traffic Safety Administration began looking into a new feature in Tesla cars that allowed drivers to play video games on a large touch-screen while the vehicles are moving. Auto experts were concerned that the games could pose a safety risk by distracting drivers, indicating a potential hardware-related failure due to the design of the touch-screen interface [122661]. (b) The software failure incident related to software can be observed in the article where Tesla released a software update over the summer that included a new video game feature allowing drivers to play games while the car is in motion. The software update added games that could be played by a driver or a passenger in full view of the driver, raising questions about safety and distraction, indicating a software-related failure in the design and implementation of the software update [122661].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident in this case does not appear to be malicious. It is related to a potential safety risk caused by a new feature in Tesla cars that allows drivers to play video games on a large touch-screen while the vehicles are moving. The concern is that this feature could distract drivers and pose a safety risk on the road [122661]. (b) The software failure incident is non-malicious as it is not related to any intentional harm to the system but rather a design flaw or oversight in the implementation of the video game feature in Tesla cars.
Intent (Poor/Accidental Decisions) poor_decisions, accidental_decisions The software failure incident related to the Tesla video game feature allowing gameplay while the car is in motion can be attributed to both poor decisions and accidental decisions: (a) poor_decisions: The incident can be linked to poor decisions as Tesla introduced a software update that enabled gameplay while the vehicle is moving, potentially distracting drivers and posing safety risks [122661]. (b) accidental_decisions: On the other hand, the incident can also be associated with accidental decisions as the warning message displayed before starting the game indicates that playing while the car is in motion is only for passengers, suggesting an unintended consequence of allowing gameplay for drivers [122661].
Capability (Incompetence/Accidental) development_incompetence, accidental (a) The software failure incident related to development incompetence can be seen in the case of Tesla's new feature allowing drivers to play video games on a large touch-screen while the vehicles are moving. The National Highway Traffic Safety Administration expressed concerns about the safety risk posed by the games distracting drivers, indicating a lack of professional competence in ensuring safe usage of the software feature [122661]. (b) The software failure incident related to accidental factors can be observed in the implementation of the video game feature in Tesla cars. The article mentions that a warning shows up on the screen before the game starts, indicating that playing while the car is in motion is only for passengers. However, there is nothing preventing drivers from starting a game, suggesting an accidental oversight in the design or implementation of the feature [122661].
Duration temporary The software failure incident discussed in the articles is more related to a temporary failure. The incident involves a new feature in Tesla cars that allows drivers to play video games on a large touch-screen while the vehicles are moving. This feature was included in a software update released by Tesla over the summer [122661]. The concern raised by auto experts and the National Highway Traffic Safety Administration is about the potential safety risk posed by the distraction caused by playing games while driving. The safety agency is looking into this feature and discussing it with the manufacturer, indicating that the failure is temporary and can be addressed through further investigation and potential modifications to the software.
