in a more residential setting, we have exhibit b. things being residential and all, there's a lot less impact on traffic. however, you'll just have to take my word for the fact that the owner of this vehicle lives (i presume with many others) in a house with a three-car garage with an accompanying three-car-wide driveway for which this spot merely serves as overflow.
indeed, that is a metro stop sign just behind the car. indeed the car is sticking out into the street and indeed, the bus doesn't have a good space in which to pull over and pick-up/drop-off passengers safely from/to. but, really, why should anyone ever disagree with the owner of a bmw 7-series? that'd be like calling out the rich to pay more taxes.
