There’s an older guy who regularly parks in my street – I live right in centre of town – who quite obviously has some sort of degenerative illness, takes him a good 15 minutes or so to get out the car and away, one arm shaking badly and the other arm limply hanging by his side.
I doubt he’s fit to take make a quick response in driving situations, but is it my responsiblity to question this?.
I had a similar siuation a few years back as the OP, guy I worked with was an alcoholic, and drove to work. After many arguments with my conscience, I did nothing in the end. He’s since lost his licence due to taking seizures/fits, but I still think that I didn’t do the right thing…
