Car makers sold people's driving habits, location data for pennies,
say US senators

Two US senators have urged the FTC to probe and potentially prosecute
three automakers that allegedly unlawfully sold motorists' personal
data for pennies.

Senators Ron Wyden (D-OR) and Edward Markey (D-MA) sent a letter [PDF]
to the US regulator's boss Lina Khan on Friday after the pair
conducted an investigation into General Motors, Honda, and Hyundai.
The senators claim those three manufacturers sold their customers'
information to various brokers either without obtaining explicit
permission to do so or without even bothering to try.

For instance, drivers' personal information including people's
acceleration and braking readings as well as records of their
whereabouts were sold to credit agency called Verisk, we're told,
which compiled the info into so-called Driving Behavior Data History
Reports that were then sold to car insurance giants.
