My OH had PD. Luckily he recognised the point at which he was not safe to drive and I helped him to take the right steps to revoke his licence. He became completely insane not long afterwards, so we just got it sorted in time.
You are allowed to drive with PD - he did so legally to begin with. Many people with early PD are driving legitimately.
Presumably this information came from his wife - has she decided to take any steps over this? If not, try GP = although I know they are loathe to intervene.
German voters slide inexorably to common sense …
Expensive free range chicken was tasteless!
