Nissan's collision-avoidance technologies encompass both active and passive safety features. The vehicle's on-board intelligent safety system categorizes potential risks into different phases of driving, and activates various barriers to provide multiple layers of protection depending on the type of approaching risk. Based on risk data collected, the car provides suitable safe-driving prompts to the driver to help avoid the risk, and also offers a succession of other safety features as the risk approaches or in case a crash occurs. Gives new meaning to 'leave the driving to us,' eh?
