[The cyclist] wants to continue straight ahead. What is the right course of action here?

In this scenario, the cyclist wishes to continue straight ahead. According to German traffic rules, you must prioritize the safety of vulnerable road users, which includes cyclists.

If your response is to remain behind the cyclist, this is the proper action, as it ensures you do not endanger the cyclist while they proceed straight. Overtaking should generally be done with great caution and only when it is safe and legal. In situations where a cyclist is continuing straight, it's important to give them space and not attempt to overtake unless you are certain that it can be done safely and without causing any risks.

Understanding this helps you navigate interactions with cyclists on the road more carefully, ensuring compliance with traffic regulations aimed at protecting all users.
