Key Points

  • Carmakers generally can’t look at or share data from your car unless you clearly say yes in writing, and you can take that yes back easily.
  • Carmakers can still use data without asking if it’s only to improve the car’s performance or safety, like fixing a software bug or spotting a safety issue.
  • Carmakers usually can’t share your car’s data unless there’s a warrant, a court order with notice and 48 hours for you to object, or it’s needed for an emergency response.
  • It bans carmakers from giving Americans’ identifying info to certain countries, including China, Russia, Iran, North Korea, and Venezuela.
  • You’d have a right to get your car’s data in real time for free (beyond the car’s price) and share it with any third party, like a repair shop or an app you choose.

Projected impacts based on AI analysis

About 3 months after the bill is signed into law (if it becomes law).

Vehicle makers would have to start following the new data consent and data access rules.

Owners should begin seeing clearer permission screens and fewer default data grabs. Owners should also be able to access vehicle data in real time and delete stored user data without paying extra fees.

Starting when the law takes effect, then continuing as systems update.

Owners start getting stronger choices about whether data can be sold or shared, with narrower exceptions.

You may get more notices and yes/no choices, and it should be easier to withdraw permission later. Data sharing should be more limited unless you agree, except for emergencies or certain legal demands.

Within about 180 days after the bill is signed into law (if it becomes law).

A federal report maps out what vehicle data is collected, who gets it, and key security risks.

This could lead to more public detail about which companies collect what data and where it goes, and may set up future rules or standards based on the findings.
