Strategy Analytics conducted an expert evaluation of the 2015 Mercedes S-Class, with focus on the autonomous highway driving feature. When functioning properly, the feature provides a glimpse into the future of autonomous driving and all its potential benefits. Positives include a visually appealing display and smooth ride. However, the lack of a consistent warning when steering assist fails is concerning. Scattered and unintuitive controls and displays are also problematic from a first-time UX perspective.
