Why does the light stay on?

Normally this website offers answers – but here is a mystery and a question …
I have noticed that when I park GBMINI#3 and switch it off, the “P” light on the automatic transmission stays lit:

Even after the lights are off and I get out, shut the door and lock the car, the “P” light stays on.
Some “running-in-and-out-in-the-cold” experimentation reveals that the light stays on for between 3 and 5 minutes. I have no idea why.

Any ideas?

Another bad weather day

Todays predicted snow storm began around the time I was heading home in my new MINI; the light rain that had been falling all day was turning to freezing rain, layering ice on everything. The weather has now turned to light snow, enough to put a thin coating on the cars & paths but nothing serious so far (although the wind is very strong):

I suppose spring will come one day …
