In what world is a disabled person able to board a car on their own but not a bus or train? And in what world are those busses and trains not staffed with people to help? Are we talking self-driving busses and cars with wheelchair driving options as a standard?
Edit: Seems the response is for the disabled person to: JuSt SpEnD mOrE mOnEy ; but we couldn’t possibly be bothered to spend more on public transit to make it more accessible.
