2. Lane Departure Warning
Lane departure warning systems uses cameras or lasers to monitor lane markings. If the vehicle exits the lane without the correct turn signal being activated, the system sounds an alarm. Some vehicles vibrate the steering wheel or the driver’s seat as well. The system is helpful in preventing accidents due to inattentive drivers, or a driver who may be falling asleep at the wheel. The system is a double-edged sword though, as some drivers may become complacent, assuming that the system will alert them if something goes wrong, becoming less alert and possibly causing an accident. When used properly as an aid, and not as a crutch, the lane departure warning system is a very useful safety feature that is becoming more common in cars today.
