"The black Ford Explorer had a warning for the test driver at the lab in Dearborn, Michigan, last week: “It is important for you to recheck your blood glucose now.”
The driver’s blood-sugar reading was 81 milligrams per deciliter at 6:32 a.m., the robotic female voice said in the prototype demonstration. When he replied that it has fallen to 71, close to where he can have lightheadedness or blurry vision, the car instructed him to take some glucose tablets and check again after 30 minutes. Then it signs off: “Have a nice drive.”
