The world’s 19 biggest automakers have agreed to principles they say will protect driver privacy. Trade groups promised that without a court order, private information will not be sold to insurance companies or used to bombard drivers with business ads without their permission. The principles also commit automakers to “implement reasonable measures” to protect personal information from unauthorized access. Sen. Edward Markey said automakers must make security and privacy as standard as seatbelts and stereos for drivers and their vehicles for drivers. Markey plans to release the findings of an investigation into privacy and security practices in the automotive industry.”]
