A method for assisting a driver of an ego-vehicle in making use of a gap between vehicles to enter a traffic flow at an intersection is suggested, comprising the following method steps: First, other vehicles in the environment of the ego-vehicle are physically sensed using at least one environment sensor mounted on the ego-vehicle. Second, a gap size of at least one gap between two successive vehicles are calculated in a processor based on the sensor's/sensors' output. An ego-vehicle driver's gazing behavior using at least one driver sensor mounted on the ego-vehicle is observed and analyzed and an assistance signal is generated based on the result of the analysis and the determined size of the at least one gap. Finally, a recommendation or warning perceivable for the ego-vehicle's driver is output in accordance with the assistance signal.
