Very interesting article. I am an older person and, evidently, when one reaches a certain age in the state where I live in the USA you must get checked by a doctor in order to continue to drive. I went for the appointment and, since he was a specialist and does that type of checkup and I had not had to see him before, he asked me a few questions and said he would have to write my primary doctor, who had already told me his office didn't do a checkup for driving. He wrote my primary doctor and got my records and sent me a bill for over $300. I am on a fixed income and that seemed really over the top to me for the service provided.
