For most of trucking history, a driver's record of where he had been and how long he had driven was a paper logbook. The industry nicknamed them comic books, because paper logs were easy to fill in creatively.
That detail matters because some of the most important data infrastructure in American freight came from a federal rulemaking about those logbooks. It did not come from a startup or a technology company.
A rule about logbooks
In December 2015, the Federal Motor Carrier Safety Administration published the electronic logging device rule.1 The goal was simple and sensible: enforce hours-of-service limits so tired drivers stop driving. Paper logs were easy to fudge. An electronic device wired to the engine is not.
The rule phased in over four years. Carriers had to install compliant ELDs by December 18, 2017, and trucks running older automatic recorders were given until December 16, 2019.2 By the end of that decade, roughly 3 million drivers were logging their hours on a connected device, and FMCSA expected the change to save the industry more than a billion dollars a year, mostly in paperwork and crashes avoided.3

The side effect is what matters for the physical economy. To log hours, an ELD has to know when the engine is running, how far the truck has moved and where it is. So the rule put a GPS-connected computer into nearly every interstate truck in the country, recording position, miles and duty status around the clock.
A rule written to enforce driver rest also produced something nobody had before: a live, machine-readable map of where American freight capacity is.
Then 2020 happened
For a few years, that data mostly served compliance. Then the pandemic arrived and the entire country took a crash course in supply chains, from port congestion to empty shelves.
Trucking had one of the strangest years in its history. Demand swung from collapse to a buying frenzy in a matter of months, and by late 2020 the national dry van spot rate had climbed to about $2.35 a mile, its highest in five years.4 Every shipper wanted to know exactly where its freight was, and a phone call to the driver stopped being an acceptable answer.
So carriers started sharing what their ELDs knew. Location feeds that used to stay inside a fleet's office got piped, with permission, to shippers, brokers and tracking tools. Live tracking went from a premium feature to the price of admission.
When the market swung the other way and rates fell, the lesson flipped too. Carriers who had spent 2020 turning freight away suddenly cared about every empty pallet position on every trip. Same data, new question: where is the space I am not getting paid for?
The start of a context layer
Put those two shocks together and something new exists. For the first time, a large share of America's freight capacity is reporting where it is, how long its driver can keep driving and where it is headed, live, in a format software can read.
That is the beginning of what I call a physical context layer: a machine-readable description of the real world that software and AI can reason about. China built its matching layer by putting an app in every driver's pocket. America got a sensor wired into the engine of nearly every truck, by regulation, and then a pandemic taught everyone to share it.
What coordination needs Added by Oway and IOI
- Open space and load factor
- Freight already on board
- Authority, insurance, equipment
- Dock windows and facility hours
- Price both sides accept
What an ELD knows In nearly every cab since 2019
- Location
- Miles and engine hours
- Duty status and hours left
Oway.
It is only the beginning, though. An ELD knows where the truck is and how long the driver can drive. It has no idea what is inside the trailer, what the truck is allowed to carry, how much room is left or what the plant down the road needs moved today. The load factor, the thing that actually matters, is invisible to it.
That is the layer we went after. When carriers connect to Oway through their ELDs, Juno combines encrypted location and route data with what it knows about the freight already on board. It can see where open space is right now and where it will be in an hour. On active lanes, that means a truck at a shipper's dock in about 30 minutes on average.
What it taught us
A regulation meant to enforce driver rest became one of the most important freight data projects in American history, without anyone designing it to be one.
It also taught us how much is still missing. Location is one signal. Coordination needs all of them: capacity, constraints, timing, cost and trust, shared across companies that do not want to give up their position. That is the problem the next note is about.
