On Tuesday, voters in Massachusetts chose, by an overwhelming majority, to extend the state's automotive "right to repair" law to cover connected-car platforms and telematics services. As a result, the state will require that from 2022, all new telematics-equipped vehicles be accessible via a standardized open-data platform that allows owners and third-party repair shops to access vehicle data from mobile devices.

Massachusetts' automotive "right to repair" law was the first in the nation when originally passed in 2013. The aim was to fight the growing problem of automakers restricting their proprietary diagnostics tools to anyone other than official franchised dealer networks. When the law came into effect in 2018, it required that every vehicle sold in the state has a "non-proprietary vehicle interface device" for accessing mechanical data.
