A ballot measure passed by 75% of voters in Massachusetts has resolved a thorny question that could have widespread implications for the automotive industry: once a person buys a vehicle, they own all of its data.

The measure, listed on the ballot as Question 1, amends and broadens a law that gives consumers in Massachusetts the right to repair the vehicles they own. The measure will require automakers that sell vehicles with telematics systems in Massachusetts to equip them with a standardized open data platform beginning with model year 2022. This standardized open data platform has to give vehicle owners and independent repair facilities direct access and the ability to retrieve mechanical data and run diagnostics through a mobile-based application.
