Location and surveillance technology permeates the driving experience. Setting aside external technology like license plate readers, there is some form of internet-connected service or surveillance capability built into or on many cars, from GPS tracking to oil-change notices. This is already a dangerous situation for many drivers and passengers, and a bill in California requiring GPS-tracking in digital license plates would put us further down this troubling path. 

In 2022, EFF fought along with other privacy groups, domestic violence organizations, and LGBTQ+ rights organizations to prevent the use of GPS-enabled technology in digital license plates. A.B. 984, authored by State Assemblymember Lori Wilson and sponsored by digital license plate company Reviver, originally would have allowed for GPS trackers to be placed in the digital license plates of personal vehicles. As we have said many times, location data is very sensitive information, because where we go can also reveal things we’d rather keep private even from others in our household. Ultimately, advocates struck a deal with the author to prohibit location tracking in passenger cars, and this troubling flaw was removed. Governor Newsom signed A.B. 984 into law. 

Now, not even two years later, the state’s digital license plate vendor, Reviver, and Assemblymember Wilson have filed A.B. 3138, which directly undoes the deal from 2022 and explicitly calls for location tracking in digital license plates for passenger cars. 

To best protect consumers, EFF urges the legislature to not approve A.B. 3138. 

Consumers Could Face Serious Concerns If A.B. 3138 Becomes Law

In fact, our concerns about trackers in digital plates are stronger than ever. Recent developments have made location data even more ripe for misuse.

• People traveling to California from a state that criminalizes abortions may be unaware that the rideshare car they are in is tracking their trip to a Planned Parenthood via its digital license plate. This trip may generate location data that can be used against them in a state where abortion is criminalized.
• Unsupportive parents of queer youth could use GPS-loaded plates to monitor or track whether teens are going to local support centers or events.
• U.S. Immigration and Customs Enforcement (ICE) could use GPS surveillance technology to locate immigrants, as it has done by exploiting ALPR location data exchange between local police departments and ICE to track immigrants’ movements.  The invasiveness of vehicle location technology is part of a large range of surveillance technology that is at the hands of ICE to fortify their ever-growing “virtual wall.” 
• There are also serious implications in domestic violence situations, where GPS tracking has been investigated and found to be used as a tool of abuse and coercion by abusive partners. Most recently, two Kansas City families are jointly suing the company Spytec GPS after its technology was used in a double-murder suicide, in which a man used GPS trackers to find and kill his ex-girlfriend, her current boyfriend, and then himself. The families say the lawsuit is, in part, to raise awareness about the danger of making this technology and location information more easily available. There’s no reason to make tracking any easier by embedding it in state-issued plates. 

We Urge the Legislature to Reject A.B. 3138  

Shortly after California approved Reviver to provide digital license plates to commercial vehicles under A.B. 984, the company experienced a security breach where it was possible for hackers to use GPS in real time to track vehicles with a Reviver digital license plate. Privacy issues aside,  this summer, the state of Michigan also terminated their two-year old contract with Reviver for the company’s failure to follow state law and its contractual obligations. This has forced 1,700 Michigan drivers to go back to a traditional metal license plate.

Reviver is the only company that currently has state authorization to sell digital plates in California, and is the primary advocate for allowing tracking in passenger vehicle plates. The company says its goal is to modernize personalization and safety with digital license plate technology for passenger vehicles. But they haven’t proven themselves up to the responsibility of protecting this data. 

A.B. 3138 functionally gives drivers one choice for a digital license plate vendor, and that vendor failed once to competently secure the location data collected by its products. It has now failed to meet basic contractual obligations with a state agency. California lawmakers should think carefully about the clear dangers of vehicle location tracking, and whether we can trust this company to protect the sensitive location information for vulnerable populations, or for any Californian.
