At a red light in a built-up area, another driver apparently wants to provoke you into a street race. What should you do?

You chose to totally ignore the provoking behavior, which is the correct response. According to German traffic rules, engaging in a street race or any form of aggressive driving is dangerous and illegal. Ignoring provocations helps maintain safety for everyone on the road and prevents escalation. Accepting the challenge or confronting the other driver can lead to accidents and legal consequences. The best practice is to stay calm, focus on the traffic rules, and avoid any behavior that could lead to reckless driving.
