This nissan car is equipped with features named, pro-pilot assist (ppa), intelligent cruise control (icc) and emergency brake assist (eba). when engaged, it is supposed to keep lanes and follow distance if there is a car in front. when the car in front is stopped this car is supposed to stop as well. ppa when engaged, if there are good road markings, will show a green stearing on the dash board, to show that car can steer it self. however if there is a car stopped in front on the same lane (ex. stopped for a red light), this car do not detect that there is a car stopped, and keep going forward until crash into the stopped car, driver have to intevene to stop at this time to stop. i took car to dealer and they said this is normal. that is not what nissan advertise. this behavior is quite dangerous of these cars, and my expectation is the car need to stop if there is an obstruction in the road, when the green steering wheel on dash is showing that car is doing auto-steer.
