If warrants were required to search cellphones -- thanks to their ability to store all sorts of personal information -- it stood to reason warrants should be needed to access other data not visible to the naked eye. > Extracting and interpreting the information from a car’s black box is not like putting a car on a lift and examining the brakes or tires. Because the recorded data is not exposed to the public, and because the stored data is so difficult to extract and interpret, we hold there is a reasonable expectation of privacy in that information, protected by the Fourth Amendment, which required law enforcement in the absence of exigent circumstances to obtain a warrant before extracting the information from an impounded vehicle.
