Tesla has announced that every car it manufactures will now come equipped with the “hardware needed for full self-driving capability.” But it’s also taken the opportunity to ease off the pace of deployment of Autopilot, its autonomous driving software.
Every new Tesla, including its forthcoming affordable car, the Model 3, will now come equipped with more sensors than previous models. The biggest upgrade is to the camera system—the cars will feature eight cameras dotted around the vehicle, as opposed to the single unit previously fitted behind the rear-view mirror, providing a 360-degree view of the world.
Elsewhere, sensors are being upgraded rather than added. The ultrasound sensors around the car will boast an increase in range to almost 500 meters, alongside a single forward-facing radar system. The data from these sensors will be processed by a so-called Tesla Neural Net running on a computer powered by Nvidia's Titan GPUs—claimed to be 40 times faster than the hardware used in previous models.
The decision to beef up the cars’ camera systems is an intriguing choice. In the wake of this year’s fatal Tesla crash involving Autopilot, Elon Musk said he made a decision to increase the emphasis placed on the radar systems as part of an upgrade to the self-driving software. “The most significant upgrade to Autopilot will be the use of more advanced signal processing to create a picture of the world using the onboard radar,” the company said at the time.
The addition of seven cameras and very little change in the radar system seems at odds with that. Some people working in the industry suggest that lidar sensors may be a safer option than optical and radar sensors, and may have expected them to be part of the new announcement, but Musk has been outspoken about his dislike of the technology. “I'm not a big fan of lidar; I don't think it makes sense in this context,” he’s said in the past.
Perhaps the most striking detail about the upgrade, though, is that despite being laden with new sensing technology, the cars won’t offer any Autopilot function at first. “Before activating the features enabled by the new hardware, we will further calibrate the system using millions of miles of real-world driving,” the company says. “While this is occurring, Teslas with new hardware will temporarily lack certain features currently available on Teslas with first-generation Autopilot hardware.”
That means that if you buy a new Tesla from a dealer in the near future, you won’t be able to use features, such as emergency braking and active cruise control, that are currently available to Tesla owners. Instead, the features will be provided as over-the-air updates at some point in the future. That essentially leaves current Autopilot users as guinea pigs and allows Tesla to take as long as it needs to ensure that future software is safe. The decision may be an attempt to slow the frenetic pace of self-driving development at Tesla, which has been criticized as risky in the past.
Even so, Musk is still keen to push the limits of what his cars can do in private testing. Alongside the announcement, Tesla showed off a video (see above) of one of its cars autonomously navigating suburban roads, highways, and the company’s own parking lot. In fact, Musk has even promised that a Tesla will drive itself from Los Angeles to New York by the end of 2017. How long you have to wait to be able to do the same remains to be seen.
