A month ago, we were driving on the highway through snow showers up to nh to go skiing, with our nifty adaptive cruise control on, when I realized that we were accelerating into the car in front of us. I assumed that the front sensor was covered in slush, took off the cruise control and drove manually. Only about 5 minutes later did the dashboard alert notify me that the front sensor wasn't working. Brought it into the dealer. They couldn't find anything wrong. Here's the problem: the car says "trust me. If you use my cool safety systems, I'll keep you from hitting the car in front of you. . . And should something disable the sensor that carries out this function, I'll let you know, so that you won't depend on me. " but that's not true. And, a driver who assumed that the car was keeping its promise, as it does most all the time--might not have realized that it wasn't until they hit the car in front of them.
