When you buy a car today, you’re not just buying steel, rubber, and glass. You’re buying rolling software – a networked computer that constantly records what it’s doing and often beams that data back to the manufacturer.
According to repair and data-recovery YouTuber Louis Rossmann, major automakers now want to use copyright law to make sure you can’t legally get at that data yourself — even if it’s sitting inside a car you own outright.
In a recent video breaking down the Digital Millennium Copyright Act (DMCA) and the auto industry’s lobbying, Rossmann warns that accessing your own vehicle’s telematics data by bypassing a digital lock could, under current law, be treated as a federal crime punishable by three to five years in prison. And instead of fighting that idea, he says, carmakers are leaning into it.
The DMCA Jumps From Pirated Movies To Car Repairs
Rossmann frames the entire debate around what he calls “the lies that uphold” the DMCA’s anti-circumvention rules – specifically the section that makes it illegal to break a digital lock, even for a lawful purpose like repair.
He notes that this part of the DMCA was written in the late 1990s to fight online piracy, not to control who can fix a car, a tractor, or a medical device. But because the law doesn’t care why you bypass a lock, only that you did, automakers can lean on it to treat reverse-engineering a vehicle’s software or data systems as a felony.
Rossmann points out that the Copyright Office has to grant special exemptions every three years just to keep ordinary repair work from being technically illegal.
And in this round, he says, the auto industry’s trade group is arguing hard against expanding those exemptions to cover more access to telematics data – the historical and real-time information modern cars quietly collect on their own operation.
The stakes, as Rossmann describes them, are stark: “We’re not saying the automaker has to give you anything,” he says. “We’re saying that if you or a third party come up with a tool to read your own data, you shouldn’t go to federal prison for 3–5 years.”
“Self-Regulation” On Telematics – Or Carefully Crafted Weasel Words?
To understand how automakers justify their stance, Rossmann walks viewers through testimony by Mark Humphrey, who spoke on behalf of the car industry in the Copyright Office hearings. Humphrey, he says, points to a 2014 memorandum of understanding (MOU) and a newer “data sharing commitment” as proof that manufacturers already give fair access to repair data.
Humphrey even cites a Federal Trade Commission report praising the auto MOU as a model of industry self-regulation. On the surface, that sounds reassuring.
But Rossmann zooms in on what comes next in the very same FTC document. Immediately after praising the MOU, the report notes that it does not truly cover telematics – the connected, over-the-air data systems that newer vehicles rely on.
That gap, he explains, is exactly why Massachusetts voters passed a ballot initiative in 2020 to force manufacturers to open telematics data to independent shops and car owners.
Rossmann’s point is simple: when industry spokespeople highlight the flattering sentence and ignore the paragraph that follows — the one explicitly saying telematics access is missing — they’re not simply mistaken. In his view, they are deliberately cherry-picking evidence to claim the system is working when the regulators themselves say there’s a hole.
He’s even more skeptical of the MOU itself. Rossmann reminds viewers that a memorandum of understanding is not a binding contract; it’s essentially a promise. “This is not a legal obligation,” he says. “It’s like a promise in a movie that can be broken at any moment with no real consequence.”
Who Decides What You “Need” To Fix Your Own Car?
When Rossmann digs into the actual wording of the automakers’ data-sharing commitment, he says the core problem jumps off the page.
The document says manufacturers will share specific telematics data “to the extent it is needed to complete a repair” and if that same information is already provided to authorized dealers. On its face, that might sound fair – but Rossmann zeroes in on a crucial question: who decides what’s “needed”?
According to him, the answer is the automakers themselves, the very entities who profit when repairs are funneled back to franchised dealers instead of independent shops.
To illustrate how dangerous that “need” standard can be, Rossmann compares it to dealing with insurance companies. A doctor may say a treatment is necessary for a patient to live a full life, but the insurer may only approve what’s absolutely required to survive or get from the bed to the bathroom. Everything else is dismissed as not “medically necessary.”
He argues the same game can be played with repair data. Technically, an independent mechanic might be able to fix a car without detailed logs or schematics by trial and error, replacing part after part until something works. But that doesn’t make the work efficient, affordable, or high-quality.
If automakers can say, “You don’t need this data; you just want it,” Rossmann says they can quietly keep telematics locked down while claiming they’re honoring the spirit of the MOU.
From a consumer perspective, that’s a big deal. Without usable diagnostic data, you’re more likely to hear “we’ll just swap the whole module for $1,000” instead of “we replaced the 5-cent component that actually failed.”
OBD2 vs. Telematics: Why Historical Logs Matter
Rossmann also draws a sharp line between what the on-board diagnostics port (OBD2) can provide and what telematics systems actually store. The OBD2 connector, he explains, is good at telling you what’s wrong right now – current error codes, live sensor readings, and so on.
But many car problems aren’t constant. A check-engine light can flick on for a few seconds and then disappear before you get to the shop. Intermittent stalling, misfires, or electronic glitches can leave no obvious trace by the time a mechanic inspects the vehicle.
That’s where telematics comes in. According to Rossmann, those systems can store historical logs of what the car was doing at the exact moment a warning light appeared: temperatures, voltages, system states, and other details that make it much easier to pinpoint the real failure.
He compares it to his own work repairing MacBooks. If he has access to a full system log, he can see whether a crash was triggered by the CPU, GPU, or some other component. Without that log, he’s forced to guess, potentially replacing entire boards when a single capacitor was the culprit.
For car owners, the difference is money and trust. If only the dealer can see the full telematics history remotely, they can diagnose problems without you ever driving onto their lot — while the independent shop you prefer is stuck in the dark unless you physically bring the car in and hope the fault repeats itself.
Rossmann sees that as a built-in competitive advantage that has nothing to do with skill and everything to do with who controls the data.
A 1990s Law In A World Of “Smart” Cars
Beyond the immediate fight over telematics, Rossmann circles back to the broader issue: the DMCA itself. He notes that the anti-circumvention rules were written almost 30 years ago in a world where the biggest worry was ripped DVDs and file-sharing on dial-up connections.
Since then, he points out, the law has utterly failed to stop piracy – even his “computer-illiterate” relatives can figure out how to download a movie in under two minutes. What it has done, he argues, is give manufacturers a powerful legal weapon to maintain control over products after the sale.
In 2025, your car, thermostat, baby monitor, and even toaster may all phone home to the company that built them. That constant connectivity means companies can lock features behind software, remotely disable products, or restrict access to internal data – then lean on the DMCA to threaten anyone who tries to break those locks with prison time.
Rossmann says his Fulu Foundation is pushing to reform what he calls section 121 of the DMCA – the anti-circumvention provisions – so that people are not treated like criminals for accessing or reverse-engineering what they already own.
He stresses that this isn’t about forcing automakers to hand over trade secrets; it’s about making sure ordinary people don’t face three to five years in federal prison for building or using tools that read their own vehicle data.
From a policy perspective, it’s hard to argue with that basic line. You may or may not care about tweaking engine maps or running your own diagnostics, but the underlying question Rossmann keeps coming back to is simple:
Is the data inside your car yours – or the manufacturer’s?
Right now, he says, the industry is acting like it owns that data outright and is lobbying to keep it that way, even if it means criminal penalties for drivers and independent repairers who dare to look behind the digital curtain.
Whether lawmakers and regulators accept that logic will decide not just what happens to your next repair bill, but what “ownership” really means in a world where everything you buy comes with a lock, a license agreement, and a threat attached.
