I was surprised to learn recently - and it may just be one of the rideshare companies in one country, or it may be more widespread - that the driver may not be told the final destination until they have accepted and started the ride.

So you might keep doing loops back to the airport (or a good restaurant precinct) because most of the jobs are OK; but it’s only when I hop in the car for a $10 ride to the next suburb that you discover you’ll lose money on this ride.
