How can lane changing assist help you in this situation without steering override?

Your answer is correct because a lane changing assist system in German traffic rules is designed primarily to warn the driver of a possible collision with vehicles in adjacent lanes, especially when the driver signals a lane change. It does not independently perform the lane change nor does it automatically brake in this situation without steering override.

The system helps increase safety by alerting you through warnings (visual, audible, or tactile) if there is a vehicle in the adjacent lane that might be in your blind spot or too close for a safe lane change. This allows you to make a better-informed decision.

In summary, the lane changing assist supports the driver by warning of dangers during a lane change, but the driver remains responsible for steering and controlling the vehicle. This rule helps avoid accidents by improving situational awareness rather than replacing driver control.
