Test-driving Infiniti’s new autonomous features

Renault-Nissan’s new Infiniti Q50 boasts a variety of new autonomous systems, including front-end collision warning, blind-spot detection and fully autonomous highway driving, Brian Dumaine writes, as he recounts his experience test-driving the hybrid electric version of the model. Dumaine writes that the Adaptive Cruise Control and Active Lane Control systems kept the car from drifting into other lanes, but also allowed the driver to take control when needed.
