To answer my American friends, yes, I do use the Parking brake at lights if they are on for any time.
It is not difficult, it's courteous to those behind, sensible, and more safe. When parking it is completely in accordance with the manufacturers advice. Indeed, they specifically state that you can damage the transmission if you let the car rest on it. I suggest you check all your manuals, Tom!
As to the Cadillac comment, I thought this was a Soul EV forum? As it happens the Soul EV is an automatic release too, which makes it very easy to use.
But even if you think I'm ignorant of such things, the very first car I personally owned was a Camaro Z28, automatic, left hand drive with pedal operated parking brake and I behaved then (even though I was a callow 19 year old) exactly as I do now; it's called driving correctly.
