Right after golf legend Tiger Woods was terribly harm in a February rollover crash in Southern California, investigators executed a warrant to retrieve information from the recorder in the mangled Genesis SUV he was driving.

The crash and the situations around it obtained intercontinental news protection, but the existence of an “event knowledge recorder” (EDR) wasn’t exceptional to Hyundai’s luxury line of Genesis vehicles.

Given that getting conventional problem for new cars and trucks, the recorders have sparked privacy problems and wound up at the center of courtroom instances. Although the NHTSA claims the crash data gleaned from EDRs in vehicles throughout the place allows officers boost safety for potential motorists, privacy gurus have expressed problem about what authorities can do with the information, in accordance to Client Stories.
