Lane Keeping Feature is Dangerous
 The vehicle frequently strays out of lane even when lanes are clearly marked. When the feature is used there is added strain and stress on the driver since there is no predicting when the car will leave the lane to oncoming traffic or obstacles. The manual and videos say system can be used to over 100 mph and in traffic, and will provide a more relaxed and rested experience. DO NOT PURCHASE VEHICLE WITH THIS FEATURE because it is too dangerous to use.
