Carmakers doing little to protect the vast amounts of data that vehicles collect, study shows

Boston — Cars are getting an "F" in data privacy. Most major manufacturers admit they may be selling your personal information, a new study finds, with half also saying they'd share it with the government or law enforcement without a court order.

The proliferation of sensors in automobiles - from telematics to fully digitized control consoles - has made them prodigious data-collection hubs.

But drivers are given little or no control over the personal data their vehicles collect, researchers for the nonprofit Mozilla Foundation said Wednesday in their latest "Privacy Not Included" survey. Security standards are also vague, a big concern given automakers' track record of susceptibility to hacking.
