How much does inattentive driving increase when Tesla's 'autopilot' is turned on?
The driving support system 'Autopilot' installed in Tesla vehicles is a function that assists speed and steering wheel operation in the lane according to traffic conditions, but in recent years, traffic caused by Tesla vehicles with autopilot turned on The accident is regarded as a problem. Meanwhile, a research team at the Massachusetts Institute of Technology (MIT) based on driving data of more than about 500,000 miles (800,000 kilometers), 'How much will the driver's look away increase if the autopilot is turned on in a Tesla car?' Was investigated.

There's a Pretty Glaring Issue With Tesla's Autopilot, Says New Study

The autopilot is a function that assists a part of the driving operation, and the driver is intended to keep holding the steering wheel. However, some drivers overconfidently trust the autopilot and tamper with their smartphones while driving, trick sensors into leaving the driver's seat, and report that 'the autopilot may misidentify the lane.' It has been. In August 2021, the National Highway Traffic Safety Administration (NHTSA) of the U.S. Department of Transportation issued 765,000 units following a series of accidents in which Tesla vehicles with autopilot turned on collided with stopped emergency vehicles. We have started a survey of Tesla vehicles.

Meanwhile, Tesla repeatedly claims in its regularly published safety report that 'autopilots reduce road accidents.' 'The odds of a Tesla car using an autopilot in an accident are close to one-tenth that of the average car,' Elon Musk said in a tweet quoted from a report released in April 2021. I did.

As part of ongoing research into car driving and technology, the research team analyzed the posture and facial position of the drivers driving the Tesla Model S and Model X to identify where the driver's line of sight is. Collected data. Then, from the total of more than 500,000 miles of driving data collected since 2016, we investigated how the line of sight changes depending on whether the autopilot is off or on.
As a result of the survey, the percentage of drivers who 'look at a place unrelated to driving operation for 2 seconds or more continuously' was 4% when the autopilot was off, but it increased to 22% when the autopilot was turned on. Turned out to jump up. When the autopilot was turned off, the driver was more likely to look at the side mirrors and rearview mirrors, but when the autopilot was turned on, the research team said that they had more time to look at the screen in the center of the dashboard. Says.
'This behavioral change can be caused by misunderstandings about what the system can do and its limitations, which is enhanced when driving automation is successful,' the research team said. The autopilot only plays a role of supporting driving, but since the driver is overconfident in the autopilot, when it is turned on, it clearly stops paying attention to driving.

Regarding the problem that the driver's line of sight changes when the autopilot is turned on and off, the research team proposed that 'the autopilot should monitor not only the road but also the driver's posture and line of sight, and in some cases issue a warning.' I am. Car and Driver, an automobile-related media, is a mechanism that warns that GM's driving support system 'Super Cruise' and Nissan's 'ProPilot 2.0' detect the driver's line of sight with infrared rays and find a tendency to distract. He argued that Tesla's autopilot might need a similar system.
