Parking
So, the 20 minute free on-street parking in Canterbury that I use occasionally is about to become 30 minute parking. Which will actually be handy, since I park there while getting my hair cut, and 20 minutes is touch-and-go. But what happens now if I'm there for 30 minutes and 5 seconds -- can I claim over-zealous enforcement, and should there be some leeway on the leeway? What people really want is to have 10 minutes longer than they thought they had, and it's not actually possible to do that.
