Here’s a car that serves as its own backseat driver, letting you know that it’s time for a break when your driving gets sloppy. The Attention Assist system monitors 70 parameters, including speed, longitudinal and lateral acceleration, turn-signal and pedal use, and steering behavior. If the system detects signs of drowsiness—such as the sharp corrections of a driver nodding off and drifting between lanes—it emits an audible warning and a visual alert. Should all else fail, and sensors detect movements that indicate a crash, the E350’s Pre-Safe system will tighten the front seat belts, and, in the case of a possible rollover, shut the sunroof and side windows for additional protection. Adding an extra layer of protection, the Night View Assist thermal technology can detect human forms up to 300 feet ahead.
