A big rig just hit 55 mph on a Florida highway without anyone in the cab

First Unmanned Test On Public Highway

If you were driving along the Florida Turnpike recently and happened to see a big rig motoring along without anyone behind the wheel, then no, your eyes were not deceiving you.

A system built by San Francisco-based Starsky Robotics powered the driverless truck to speeds of 55 mph along 9.4 miles of public road earlier this month. It’s thought to be the first time a heavy-duty commercial truck has been allowed on a public highway without anyone behind the wheel.

Starsky CEO Stefan Seltz-Axmacher said his company is competing with the likes of Waymo and TuSimple — which still use safety drivers in their autonomous trucks — by taking a different approach to how it incorporates its technology into large vehicles.

Instead of developing entirely autonomous systems to steer the trucks, the company is using remote human drivers to navigate the vehicles along more complicated sections of road between the depot and the highway.

As you can see in the video at the top, the driver uses a bank of monitors showing live-streamed footage from a bunch of cameras attached to the truck’s exterior, and steers the vehicle using a regular-looking steering wheel. Yes, it’s a bit like a video game, except there’s a massive truck somewhere far away that you’re actually controlling.

“We know that today, humans are far better at navigating many of the nuances of driving than even the most advanced computer systems, which is why we use remote drivers to help the trucks at their most contextually complex junctures,” Seltz-Axmacher wrote in a recent post.

The CEO added: “We’ve built a highly reliable highway automation system which we’ve combined with a teleoperation capability that allows our remote drivers to navigate trucks between distribution centers and the highway. This novel combination of complementary technologies — significantly improved, verified, and validated — is what has allowed us to make history.”

You might be wondering what the point is of having a driver in an office when he or she can be in the actual cab, but as Starsky’s technology develops and automated systems become more common, the likelihood is that fewer remote drivers will be needed. With truly driverless big rigs still some ways off, Starky’s system could be a bridge to such a time, and help to deal more immediately with the growing driver shortage affecting the truck industry.

Since its launch three years ago, Starsky has been moving steadily toward its recent accomplishment of driving an unmanned truck at 55 mph on a public highway, having already completed driverless trips with safety drivers, as well as a driverless outing last year that saw its truck reach 25 mph on the same Florida highway as the recent test, although it was closed to other traffic at the time.

Moving forward, Seltz-Axmacher says the plan is to increase the frequency of the unmanned drives and expand Starsky Robotic’s fleet of trucks to become “the most reliable driver in your rearview mirror,” as he puts it.

Scout Motors Electric SUV: rumored price, release date, design, and more
Scout SUV Teaser

There's another electric SUV on the way, and this one comes with a familiar name. Volkswagen is reviving the classic Scout name for a new electric SUV that's billed as being an "RUV," or a rugged utility vehicle. And, it could well prove itself as the best electric SUV in its price range, when it does finally come out.

The new EV isn't due out for quite some time, but there's already a fair bit that we know about it. Curious to learn more? Here's everything you need to know about the upcoming Scout SUV.
There's very little we actually know about the Scout SUV so far, but we do know a little about the eventual design. A few teasers for the upcoming vehicle have been released, showing sketches of both the SUV and the accompanying pickup truck, along with what's presumably the front of the SUV -- though in a dark environment, with little detail.

Volkswagen reinvented one of its most iconic models with the ID.Buzz, a modern, all-electric homage to the classic Microbus. But that's not the only fan favorite vehicle currently in the automaker's catalog.

Debuting at the 2023 Munich Auto Show, the Volkswagen ID.GTI concept aims to do for the Golf GTI hot hatchback — VW's signature performance car — what the ID.Buzz did for the Microbus. VW claims a production version has already been given the green light, although it won't say when it will appear.

Some Tesla fires were reportedly caused by Idalia floods

As Florida embarks on the difficult work of cleaning up the damage caused by last week’s powerful Hurricane Idalia, local fire crews warned owners of electric cars caught up in floods to immediately move their vehicles away from buildings as a safety measure.

The alert was issued via the Facebook account of firefighters in Palm Harbor, Florida, after reports emerged of electric batteries in two Tesla cars suddenly combusting after exposure to saltwater, CBS News reported, adding that one of the Tesla cars went up in flames as it was being towed by fire crews.
