Legislators and Data Privacy Experts are voicing growing concerns about the amount of data that car manufacturers and insurance companies can access and use.

Allstate ALL.N has been sued by the state of Texas, which accused the insurer on Monday of illegally tracking drivers through their cell phones without their consent and using the data to justify charging more for car insurance.
