The fact that even a Federal law as intrusive and unreasonable as the ADA does not require states to allow blind people to drive cars ought to be a lesson to anyone who insists on bending over backwards to grant people this idiotic "right" to operate a vehicle on a public roadway.
Instrusive and unreasonable according to whom? It is the law of the land.
Are you aware of the person who had to crawl hands and knees up the steps to the second floor of a public building in order to enter the courtroom for his case to be heard in Tennessee because the building was not handicapped-accessible?
Go back and read the law please if you will: The ADA is about 'reasonable accommodation'; care to dispute THAT?
It is NOT 'reasonable' from your hollow example to have blind people driving vehicles.
It IS 'reasonable' to believe people with certain physical limitations may not be able to observe the proposed law to pristinely clean their vehicles of all snow and ice (those with wheelchairs; those with heart conditions; those with other debilitating conditions), while still maintaining an overall ability to operate a vehicle in any manner other than the rest of us do on a daily basis.
I am sure the Pope you quote in your 'about page' would be very proud of the stance you have taken. It is, after all, very Catholic and very Christian, isn't it?
Maybe you need some work with disabilities' awareness and with sensitivity training. Obviously, the Pope hasn't yet touched that part of your psyche.
