There's more safety equipment available in the LS than is necessary. The usual suspects are all there–stability and traction control, front and curtain airbags–but there are also active headrests and front side and knee bags standard. There are also rear side airbags available.
The Lexus LS also features a self-parking system that steers the vehicle into a parallel or row parking spot as the driver backs up; some will find it helpful and a safety aid, but to others it's a gimmick.
Lexus now offers an Enform and Safety Connect system on subscription basis; the telematic systems notify Lexus if the vehicle is involved in an accident and summon emergency personnel automatically.
Adaptive cruise control and automatic high-beam headlamps are available once more. Among the new safety options this year are blind-spot monitors with rear cross-traffic alerts, a lane-keeping assist that nudges the car back into its lane when it senses a drift off course; and a new Pre-Collision Safety system with stereo cameras that can detect obstacles in the road ahead, with the assistance of infrared vision. With the optional system, the Lexus LS can bring itself to a complete stop if it detects trouble at speeds of up to 24 mph.
At this point, neither of the agencies that crash test cars have fully assessed the LS' safety in accidents. Thanks to its long list of active safety technologies and its excellent past test results, we've given it a high score for 2014.
