As it happens, General Motors informed its dealers that when in Valet Mode, the 2015 Corvette allows the owner to record the driving of their vehicle when the car is not in their control. The system employs a video camera, but that doesn't cross any U.S. laws. The audio recording of the PDR unit is the real issue here that might get General Motors in big trouble.
In this regard, the 2015 Chevrolet Corvette's PDR unit is illegal in those 12 states that require both parties to be aware of the audio/telephone recording. Those states are as follows: New Hampshire, Florida, California, Connecticut, Hawaii, Maryland, Massachusetts, Montana, Pennsylvania, Washington, Nevada and Illinois.
A valet's job doesn't imply much privacy, but the law applies to all and GM announced it intends to update the PDR in those 2015 Corvette vehicles in the near future. All cars currently in dealer inventory are to get a new PDR software according to CorvetteBloger, but GM also sent letters to owners of the 2015 Corvette in which they're recommended to "refrain from using the Valet Mode feature until the update takes place."
