Automobile manufacturers, long laggard in the ways of technology, have been making a push in recent years to catch up with consumer expectations. BMW is one such car maker, and it's rolling out a suite of new technologies to improve its cars at CES 2014. First up is an improvement to its suite of driver-assistance technology -- ActiveAssist -- that's been built into a new prototype car. Generally speaking, it's a series of control systems that allow the car to react "to fluctuating grip levels" like during hydroplaning to react and bring the car back under control precisely, automatically and without driver input. It accomplishes this by both braking individual wheels (like existing systems) and adjusting steering input in response to its active monitoring of road conditions using lidar, radar, ultrasound and optical cameras.
