Actually, the rideshare folks usually (depending of course on location and personal preference) are after the airport drives. It's the onesie-twosie "bar-hopping" short trips that they don't like.
That’s what I’m getting at. Airport drives are usually the best, but if you aren’t told the passenger’s destination you could be forced to go all the way out to the airport to accept a tiny fare.
Great for me as a consumer; lousy for the driver’s income; and a reason why (to answer the question asked) some drivers / riders accept loss-making fares: they don’t get told in advance how much the trip is worth.
