What's the best way to respond to cyclists who are traveling in the opposite direction and don't move out of the way? Should I then ride on the sidewalk?

Of course, you must not suddenly drive on the way;)

When someone comes to me illegally and you don’t come by, I stop and show that I’m looking forward to what he’s doing now. So with laterally laid head and drumming fingers.

What did he expect?

And if he’s so blunt that he’s just driving on a standing obstacle, I can’t do anything for falling off the bike. It’s already happening.
