And when Uber drivers arrive for a pick up at someone's house, surely
they announce themselves in the same was as any mini cab would?

Or do they just sit outside and "hope"?

My experience of (pre-Uber) minicab drivers is they just sit outside in
the road tooting the horn until someone emerges from the house. Yet
another completely illegal procedure, of course.

The only ones who actually come to the door are airline courtesy "limos"
for business class flights (and I've not had one of those for years).
