Using a Lincoln MKZ with an interior that looks an awful lot like the 2010 Ford Fusion (mostly due to the gigantic screen), a company by the name of Medtronic is developing an in-car system capable of monitoring blood-glucose levels specifically for diabetics. The diabetic-driver will wear a continuous glucose-monitoring system that will communicate wirelessly with the in-car infotainment system via Bluetooth.
It will relay information about blood-glucose levels at any given time to keep the diabetic aware and to determine if it's time for a snack. This could be a potentially life-saving vehicle addition for long-distance drivers who deal with the disease. If combined with nav we could see this system then reminding the driver where to find a healthy snack in a nearby store, and purposefully denying the existence of sugary fast foods. [Ubergizmo]
