yes, my 84 yr old mother, had a stroke in her eye and lost most of her sight in that eye, still drives no matter me telling her often not to. How she keeps her license seems to revolve around Doctor shipping, as the oldies all know the doctor to go to to get their license renewed.

She'd never take public transport if it was at her door, so you'd need something better than just good public transport, like banning everyone over 75.
