Cleaning aside, I'm surprised that having unsecured bodies in a passenger vehicle is a requisite for being a service provider.
Letting your dog loose in your own car is your own choice, but the trunk exists for unsecured cargo so in an accident, you don't have large objects flying around inside the cabin.
The correct solution would be to identify the handicapped passenger with animal and dispatch an appropriate vehicle. Instead, Uber puts both driver and passenger in danger with this policy.
I see what you're saying, but let's be realistic. Is every Uber/Lyft vehicle going to be outfitted with a wheelchair lift, just in case? That's definitely not going to happen. Most vehicles cannot accommodate a wheelchair, and the ones that can (vans) are very expensive to modify.
I am not completely wheelchair-dependent, but I cannot get into a tall vehicle (like an SUV). Last time I used Lyft, I had to call a vehicle and just cross my fingers that I would be assigned to one that would work for me. If not, I had to cancel and try again. I would much rather have a special vehicle dispatched to me than be assigned a vehicle that is inadequate.
Stereotypes notwithstanding, a lot of regulations/laws do make reasonable tradeoffs. In this case, it appears as if the ADA guidelines do require a taxi driver to help stow a wheelchair but they don't require every cab to be a van equipped with a wheelchair lift. It would be nice if Uber allowed special requests although, of course, the number of options could explode quickly and it probably doesn't fit well with the Uber automated dispatch model.
