Corvette and other Chevy models to get 4G LTE modem this year
GM has detailed a very interesting feature that is available in the 2015
. The Corvette Performance Data Recorder (PDR) has the ability to capture video, audio, and telemetry data while the driver is on the racetrack.
The 720p resolution video the car can record can be reviewed in the car when parked and downloaded to a PC for sharing via social media. The data can also be uploaded with the Cosworth Toolbox telemetry software that is similar to the software used by Corvette Racing.
“The Performance Data Recorder combines the ability to record and share drive videos with the power of a professional-level motorsports telemetry system,” said Tadge Juechter, Corvette chief engineer. “Drivers can easily record and share their experiences driving down the Tail of the Dragon or lapping Road Atlanta. In addition, with the included telemetry software, users can analyze their laps in incredible detail and find opportunities to improve their driving and lap times.”
PDR will be available closer to the start of regular production for the 2015 model year Corvette, which is set for later in Q3 2014. The PDR system includes an HD camera mounted in the windshield header trim. It records the driver point of view and picks up audio using a dedicated mic in the cabin.
The telemetry recorder has a dedicated GPS receiver operating at 5Hz making it five times faster than the GPS receiver in the vehicle’s navigation system. The telemetry system is hard wired into the car giving it access to details like gear selection, braking force, RPM, and steering wheel angle. A track mode adds a map of the track, g-force, and lap time.
Video shot with the camera is recorded to a dedicated SD card slot in the glove box making for easy transfers. GM says that a 32GB card will be able to record about 800 minutes of video.
General Motors has also announced that drivers will be able to get high-speed data via a 4G LTE modem in some Chevy automobiles later this summer. The LTE service will come via an OnStar 4G LTE connection. The vehicles that will initially have LTE connectivity include the 2015 Stingray, Impala, Malibu, and Volt. The service will enable a 4G LTE hotspot inside the vehicle for various devices to connect to the web on the go.

Car's have had black boxes going back to the 80's. REALLY good tool when figuring out who's at fault in an accident.

Restraint control modules ("black boxes") are one thing.
They measure things from speed, braking force, airbag deployment, whether a seatbelt was fastened, and in the most technical implementations radio volume, headlights off/on and windshield wipers off/on.
Adding a Camera can be a can of worms. I've used a dash cam in my vehicles for many years, but it has a easily removable (and swallow-able ;) micro SD card. I don't think Corvette's will be as quick and easy to "erase the evidence."
Court cases are open-and-shut when it comes to photo/video evidence. Telemetry from a RCM doesn't always make a clear picture.

It is stored on an SD card too.
