Disputes in two state governments highlight a growing controversy in the auto industry over the data that Internet-connected cars can produce and process.
In Massachusetts, the debate focuses on a proposed amendment to a state "right to repair" law and differences over data access between automakers and aftermarket providers.
In California, a broad new privacy law does not explicitly center on the automaker-vs.-aftermarket argument, lawyers for both sides agree. But the law includes mandates for automakers about how they collect and handle vehicle data.
