For twenty years, California has been the one state in the country where your auto insurer wasn’t legally allowed to care how you actually drive. Not the smooth highway merges. Not the death-grip braking in stop-and-go traffic. None of it.

That was never a technology problem.
What AB 311 Actually Does
General Motors already had the hardware running quietly through OnStar, and it cost the company $12.75 million and a Federal Trade Commission order to find out how quietly. The bill moving through Sacramento right now isn’t really about tracking drivers. It’s a permission slip for something the industry already built, deployed, and got caught doing without asking.
Assembly Bill 311, Assemblymember Tina McKinnor’s Consumer Driving Data Protection Act of 2026, would let California drivers voluntarily let their insurer watch how they drive: whether they keep pace with traffic instead of speeding, brake smoothly instead of abruptly, stop fully at signs and lights, and stay in their lane instead of weaving. Opt in, and roughly six months of that behavior becomes part of an official “driving safety record,” a term California’s insurance code has used since 1988 without ever quite defining. Opt out, and the existing system stands: a driving record built entirely from Department of Motor Vehicles points, assigned after the fact, after a ticket or a crash.
That distinction matters more than it looks. Under Proposition 103, the 1988 initiative that still sets the rules for every California auto policy, lawmakers can only amend it with a two-thirds vote, and only if the change furthers the initiative’s original purpose. McKinnor’s bill doesn’t try to rewrite Prop 103 head-on. It slides telematics into a term the initiative never bothered to define, and lets insurers treat it as a new flavor of “driving safety record” rather than an entirely new rating factor. It’s a clever bit of statutory jujitsu aimed at a law that has resisted more direct changes for 38 years.
Here’s the detail that should stop any car enthusiast cold: California is the only state in the country that still bars usage-based insurance rating outright. Every other state, plus Washington, D.C., has allowed some version of it for the better part of two decades. That regulatory holdout has kept an entire industry standing outside the largest auto insurance market in the nation, one that ratings agency A.M. Best says insurers are pouring investment into as artificial intelligence sharpens the underlying risk models. A bill that reads like a consumer-safety measure is also a very large invoice, one that’s been waiting to be sent to 27 million California drivers for a long time.
None of this is happening in a vacuum.
The OnStar Precedent
GM’s $12.75 million settlement wasn’t a one-off. A Florida driver’s lawsuit alleges his Toyota RAV4’s driving data reached Progressive before he ever agreed to it. The Consumer Driving Data Protection Act reads like a direct response to those scandals: it bans insurers from selling telematics data, bans combining it with outside datasets, and — this is the detail worth sitting with — bans collecting any biometric data, facial recognition, or audio and video recordings of vehicle occupants. Lawmakers had to write a specific line item prohibiting insurers from using cabin cameras, because millions of new vehicles already have them, installed to run hands-free driver-assist systems from GM, Ford and others. This bill isn’t just regulating some hypothetical future system. It’s fencing off hardware that’s already sitting in driveways.
The Discount Isn’t Guaranteed
The pitch to drivers is simple: drive well, pay less. The data says otherwise for a lot of people.
A Maryland Insurance Administration study of that state’s telematics programs found that in 2023, only 31.2% of enrolled drivers actually saw their rates drop. Another 23.6% saw an increase, and nearly half saw no change at all. Insurers aren’t chasing this technology purely out of generosity, either. Claims have simply gotten more expensive to pay out: parts inflation, heavier vehicles, and the reality that even a low-speed fender-bender now often means recalibrating a windshield-mounted camera or a bumper-integrated radar sensor rather than just hammering out a dent. Rates for California’s largest insurers have climbed more than 30% since 2022. Telematics is being sold to lawmakers as a safety tool. Inside insurance company boardrooms, it’s underwriting relief.
A Problem for Anyone Who Actually Likes Driving
There’s a narrower problem for anyone who actually likes driving. The behaviors AB 311 allows insurers to score are keeping pace with traffic, braking abruptly, rolling through stop signs and lights, and changing lanes frequently. Read that list as a track-day driver or a canyon-road regular and it gets uncomfortable fast. A confident late brake into a corner and a panicked one can look identical to an algorithm. So can a decisive, safe lane change and a genuine weave. The bill doesn’t grade context. It grades pattern-matching, scored by a model insurers don’t have to show the driver being scored — only the state’s insurance commissioner, and only because the Department of Insurance fought to get that access written into the bill at all.
Who Wins, Who Pays
This fight is bigger than one bill. The Auto Wire has tracked the last two years of vehicle data ending up in insurers’ hands sideways: through OnStar, through a State Farm and Toyota crash-data pipeline announced this month, through lawsuits nobody saw coming until a subpoena landed. AB 311 is Sacramento’s attempt to build a front door for a process that has mostly been happening through the back one.
AB 311 still needs to clear a skeptical Department of Insurance and a two-thirds legislative vote before it becomes law, and McKinnor says she’s negotiating roughly 20 pages of amendments to get there. Whatever the final version looks like, remember this the next time an automaker announces a new driver-assist camera or a new connected-car feature.
The technology was never the obstacle. The paperwork was. California didn’t need new hardware to catch up with 49 other states. It needed forty pages of statute admitting the hardware had been running the whole time.
