I live in Hamburg for 28 years.
I've never driven black in my life.
And I've actually noticed more than just once that people have driven black.
And sadly I have to say that someone who would have prejudice against a particular population group had been fully confirmed in his prejudice.
But I still realize that there is still a prejudice.
even more often, especially in "my" city in the tram and the buses.
Yes, of course, more often.
Yes, several times.
