I try to cover up as much as I can. Sunglasses are a good idea.

Regarding sunglasses in Berlin, police stopped me on my e-moped recently and forced me into a restaurant bathroom to do a pee test for drugs, and they told me the reason was that I wore sunglasses when riding and thus looked suspicious. I wear then to protect my eyes from dust and bugs. I was absolutely sober, and going home from church. My takeaway is, Berlin police want your face.
