Can a human react faster than Tesla's Autobrake system? A new game by Select Car Leasing challenges players to see if they can react to obstacles in the road that require braking quicker than Tesla's Autobrake technology.

According to Select Car Leasing, Tesla has never released the exact reaction time of its automatic emergency braking (AEB) system. To find out what time to use, the company selected 10 viral clips of the AEB system in action, slowed them down, and analyzed the reaction time frame by Fram. The average reaction time was 0.3 seconds, a time that's faster than a sky diver fall 40 meters.

Human perception time varies greatly depending on a number of factors like age, eyesight, conditions, and speed.

Tesla isn't the only company to have installed automatic emergency braking in its vehicles. The technology, which has been proven to save live and prevent accidents, is quickly becoming a standard offering across a number of makes and models by companies including Nissan and Toyota.

To test to see how your reaction time compares to Tesla's Autobrake reaction time, play the (safe for work) game here.

OTA software updates

Tesla rolls back FSD beta before issuing fix

Tesla issued a beta update but quickly pulled it back.

Tesla's Full Self-Driving tech is currently in public beta testing, which means that the automaker allows a subset of its owners to download the software to their cars. Over the weekend, Tesla released FSD beta 10.3 and users started reporting issues almost immediately. Since Tesla's PR department is essentially CEO Elon Musk's Twitter account, he took to social media to outline the process to fix problems with the beta.

Musk tweeted that public beta version 10.3 was rolled back to 10.2. "Please note, this is to be expected with beta software," he said. Issues began popping up with Tesla owners on various forums and on social media. Drivers reported that cars shut off active safety features without their input and some noted that their forward collision warnings and automatic emergency braking systems malfunctioned, causing the cars to apply the brakes without any apparent danger in the road ahead.

Early this morning, Musk tweeted again to note that beta version 10.3.1 is rolling out now, which would re-update users to the latest version with fixes. All of this illustrates how FSD is not final and has a way to go before it's ready for showtime. Developing software of any type is difficult work, made even harder by the fact that public roads are so unpredictable at times. So, while Tesla's public beta approach, which puts unproven functions into the hands of everyday drivers, may not be the most palatable for many of us on the roads at the same time, it's certainly netting the company plenty of data to work with.

Cadillac will be the first brand with Ultra Cruise

General Motors

Tesla has been in hot water for a while now for shenanigans pulled by owners abusing the automaker's advanced cruise control functions. While the company's Full Self Driving (FSD) tech isn't quite ready for primetime, other automakers are catching up – quickly. Today, General Motors announced Ultra Cruise, its advanced driver assistance tech that promises to allow hands-free driving in 95 percent of driving scenarios.

GM notes that its goal is to eventually roll the service out to all paved roads in the U.S. and Canada. When it launches, the service will work on over two million miles of roads, which could nearly double as the program expands.

Ultra Cruise will offer a host of automated driving features that build on Super Cruise:

  • Dynamic display system
  • Ability to react to permanent traffic control devices
  • Follow internal navigation routes
  • Maintain headway and follow speed limits
  • Support automatic, on-demand lane changes
  • Support left and right turns
  • Support close object avoidance
  • Support parking in residential driveways

The system uses LiDAR, radar, and cameras to build a 360-degree, three-dimensional picture of the world around it. An additional LiDAR unit is located behind the windshield. GM notes that a big part of the system is its Human Machine Interface (HMI), which communicates with the driver to alert them when they need to take control. Ultra Cruise-equipped vehicles will do this with a head-up display that helps drivers stay focused on the road, and will use the same driver monitoring cameras that are used in Super Cruise.

Ultra Cruise will first be available in Cadillac vehicles starting from 2023. There's no word on pricing or specific vehicle availability at this time.
