Inside a quiet kitchen, I drink black coffee and think about October 20, 2016. On that chilly morning, a semi-truck named Otto drove 120 miles down Interstate 25 in Colorado without a human touch on the steering wheel. Anthony Levandowski built this machine. The truck carried 51,744 cans of Budweiser beer. While the machine rolled at fifty-five miles per hour, the professional driver sat in the back cabin, reading a glossy magazine.
It was a strange, silent moment in history.
Levandowski made this happen after leaving Google, setting off a wild legal battle over trade secrets that shook the entire technology world.
This high-stakes corporate drama, however, was only the beginning of the industry's turbulent power struggles.
The Sudden Storm inside the TuSimple Boardroom
At three in the morning, boards of directors sometimes do very strange things. Xiaodi Hou founded TuSimple in 2015 with a dream of letting heavy trucks guide themselves across the desert. He holds a doctorate from Caltech and understands how machines see the physical world.
But in October 2022, his own board of directors fired him during a sudden video call, claiming he shared technology secrets with an outside startup.
The company fell into instant chaos, and Hou fought back with lawsuits, showing how fragile these massive tech empires really are. Now the company has left the American market entirely, leaving behind empty testing lanes and cold computer servers.
Yet, while some pioneers faltered in the boardroom, others shifted their focus to testing their machines on the open highways of the American South.
Chris Urmson and the Flat Texas Roads
On the flat asphalt of Texas, Chris Urmson is trying a different path. He led Google's self-driving project for years before starting Aurora Innovation in 2017. His trucks now move cargo daily between Dallas and Houston on Interstate 45. They use a special light-detecting sensor called FirstLight Lidar. This sensor emits microscopic beams of light to spot a dark cardboard box on the road half a mile away. It gives the truck fifteen seconds of extra time to make a decision, which is a lifetime for a machine.
While these modern laser-guided systems represent the cutting edge of contemporary technology, the fundamental concept of self-driving cargo vehicles actually traces its roots back to an audacious experiment in Europe decades ago.
The Secret History Of Autonomous Cargo Machines
In 1994, a German professor named Ernst Dickmanns did something almost impossible. He installed a massive computer inside a Mercedes-Benz van and let it drive on the high-speed Autobahn near Munich. The van reached speeds of one hundred and eleven miles per hour. It used simple video cameras to trace the white lines on the asphalt.
And it did this without the internet, without GPS, and without modern digital maps. He proved that machines could navigate the world using raw visual cues alone, long before Silicon Valley existed.
This early reliance on raw visual cameras laid the groundwork for a debate that still divides the industry today: how exactly should these vehicles perceive their surroundings?
The Ghostly Logic Inside The Heavy Metal Cabins
So why do we expect these giant machines to behave like saints on the road? The biggest fight in the industry is about sensor technology. Tesla uses only cheap cameras, while companies like Kodiak Robotics use a mix of lidar, radar, and cameras. Kodiak, founded by Don Burnette in 2018, uses modular sensor pods on the mirrors of the truck.
If a flying rock breaks a sensor, a human can swap the pod in ten minutes with a simple screwdriver.
This design choice is a direct critique of beautiful, unfixable designs.
Some engineers want perfect, artistic machines, but truck owners want something they can fix with a greasy wrench.
Regardless of whether companies choose modular, easily repairable sensors or complex integrated arrays, the ultimate destination for all of these competing technologies is rapidly approaching on the open road.
Where The Long Highway Meets The Horizon
By the end of 2026, Aurora plans to remove the safety driver entirely from its commercial routes in Texas. This means an eighty-thousand-pound machine will roll down the public highway next to families eating hamburgers in station wagons. Gatik AI is already doing this on shorter routes, moving groceries for Walmart in Arkansas using smaller box trucks with no humans inside.
They focus only on simple, right-hand turns on fixed paths.
It is a slow, methodical march toward a world where the driver cabin is just empty space.
As this driverless future edges closer to reality, it naturally raises urgent, practical questions about how these massive autonomous machines will operate in the messy real world.
Answering Quiet Questions Under The Open Sky
How do self-driving trucks handle heavy rain or winter snowstorms?
Cameras get blurry and lidar beams bounce off snowflakes, making the truck blind. Companies deal with this by stopping the trucks or using thermal cameras that see heat signatures through the fog. You can read more about how weather affects these sensors on Reuters.
Do autonomous trucks save fuel compared to human drivers?
Yes, they do. Computers do not get angry or impatient, so they do not stomp on the gas pedal. They maintain a steady speed and draft behind other trucks, which reduces wind resistance and cuts fuel use by about ten percent. You can find detailed fuel studies on Wired.
What happens if an autonomous truck gets a flat tire on the highway?
The truck has sensors inside the wheels to detect pressure drops. It will pull over to the shoulder automatically, turn on its hazard lights, and send a digital alert to a remote command center to call a service truck. Read more about autonomous safety systems on The New York Times.
