The driver wasn't really a good guy trying to make a living by driving this shitty cab. In fact, he was part of one of the small gangs in Craghorn.
They mostly prey on new arrivals by checking first if they were rich or not. The way they do so was by asking them to buy the list for a massive amount of money.
If they agreed in a heartbeat, the driver take them to an empty alley and stop the hovercar. Then, he would act like it broke down and exit to check the engine.
The moment he did so, he gets jumped up by his gang members and beaten up to avoid suspicion while the passenger receives a totally different treatment.
Since the gang members always moved in a pack and they were strong on their own rights, the passengers usually concede to their conditions to avoid getting killed.
That's because unlawful killing in the city was totally allowed as long as it didn't happen in public space.
