Full disclosure: I have multiple disabilities.
I have heard about too many issues about people taking advantage of those with disabilities, and even those who do not have disabilities, are taken advantage of.
I am aware of friends with disabilities relying on the word of other friends with disabilities, who will use a service by "name" but end up being taken advantage of anyhow. So the social guarantee of friends helping friends falls apart.
Please make sure that those who transport those with disabilities have background checks.
