（4）盲点检测

    盲点检测系统是一个基于雷达的系统，当有车辆和你并行时，如果它进入了你的视线盲点，后视镜上的闪灯就会闪烁，提醒你注意安全。这是个十分有用的配置，可以避免你变线时进入已经被占用的车道，也能使你免遭被人狂按喇叭和破口大骂之苦。更先进的干预系统还可以通过控制刹车使你的车子脱离危险。

4. Blind spot detection

    It's a radar-based system that detects vehicles travelling in parallel lanes and uses blinking lights in rear-view mirrors to warn when one is in the blind spot. It's very helpful in preventing you from veering into occupied space, along with the attendant horn-honking and name-calling. More advanced intervention systems apply the brakes to nudge the car out of danger.
