Does an uber driver know when they accept a ride that the rider has a dog with them?
Presumably not. Even if they did, what should they do with that information? Service dogs have special status.
They can have a fleet of vehicles with a mix of accommodations ranging from none to fully equipped for everything, as long as when a disabled person calls for a ride the company can send a vehicle, about as promptly as they can send a vehicle to a non-disabled person, that can handle that person's needs.
So if we were talking about a normal taxi company, that is one that acknowledges that they are a taxi company, then it would make sense for the company to ask when someone calls for a pickup if they have any particular requirements for the vehicle sent or will need any assistance from the driver. Then they could dispatch an appropriate vehicle.
It would also make sense to tell the driver, since sometimes there is extra work or preparation the driver has to do or special handling of the pickup or drop off.
With a taxi company like Uber that is pretending it is not a taxi company, it is a more difficult situation. If they just keep on as is, they will have more and more cases like the present case.
I only see a couple of approaches Uber can take if they don't want this to keep happening and they want to continue pretending they aren't a taxi company.
1. Only allow drivers to use Uber if they and their cars are able to handle all disabilities at all times they they are in service.
2. Allow a mix of drivers/cars like the normal taxi companies have. Users can specify what they need and Uber only shows the ride request to drivers that can handle it.
Should they tell drivers that a ride involves a disabled person? That would aid the driver who goes to handle the ride for the same reasons given earlier for normal taxis. On the other hand, it might lead to drivers giving preference to non-disabled requests, and so still land Uber in hot water. Maybe not tell the driver until after a driver has accepted the ride, with heavy penalties for cancelling after they find out?
They could also just continue as is, except offering early settlements with any disabled person who can't get service rather than trying to fight it and running the cost way up when they lose. That might be financially sensible in the short run, but it bolsters the argument that they undercut normal taxis by skimping on compliance with the law, which strengthens the case for cities to regulate them as heavily as taxis are regulated.
