Tesla is recalling nearly all of the vehicles it sold in the U.S., more than 2 million across its model lineup, to fix a defective system that's supposed to ensure drivers are paying attention when they use Autopilot. Documents posted Wednesday by U.S. safety regulators say the company will send out a software update to fix the problems. The recall comes after a two-year investigation by the National Highway Traffic Safety Administration into a series of crashes that happened while the Autopilot partially automated driving system was in use. The agency says its investigation found Autopilot's method of ensuring that drivers are paying attention can be inadequate and can lead to foreseeable misuse of the system. The recall covers models Y, S, 3 and X produced between Oct. 5, 2012, and Dec. 7 of this year.

Car systems that use increasingly sophisticated artificial intelligence (AI) could keep you safer by monitoring your driving, but some experts say AI isn't ready to replace human drivers. Toyota is developing a system called Guardian that uses a dashboard camera to check to see if a driver falls asleep. It's part of a growing movement to increase automation in vehicles, but some experts say we're a long way off from cars that are safe enough to fully drive themselves. "I've been a bit of a skeptic of full automation in terms of the timelines," MIT professor John Leonard, who is working on Guardian, said at a recent MIT Mobility Forum, according to the news release. "[It] is going to take a lot longer to have this sort of ubiquitous robo taxi fleet, whereby, you know, a teenager today would never need a driver's license or never need to have a real human Uber driver because all cars would drive themselves autonomously."

Amazon plans to install AI-enabled cameras in their delivery vehicles to monitor their drivers while they're on the clock. An Amazon video uploaded to Vimeo shows how the camera operates. The Driveri platform, supplied by the software company Netradyne, provides real-time feedback to a driver and evaluates a driver's performance during their shifts. The program's feedback notes distracted driving, failure to stop at a stop sign, speeding and others. If the camera detects any of these trigger signals, it will upload recorded footage.

OSAKA – Omron Corp. has developed a new in-vehicle sensor for monitoring drivers from real-time video and pictures. The Osaka-based automated control equipment maker aims to put the sensor into use in 2019 or 2020. The sensor, which draws on artificial intelligence, uses a camera to monitor the driver's condition. In the event of a sudden change, the sensor will sound an alarm or stop the automobile safely. The new sensor will support autonomous driving technology by offering a new method for managing a vehicle when changing driving mode from autonomous to manual safely.
