oldsmobile limosine?
I imagine that his family wouldn't let him have a real limousine because that would look bad politically for a champion of the poor & downtrodden. But I imagine they made him have a driver because they knew he would have a drunken driving accident just about every night if he tried to drive himself.
But he "borrowed" the keys like a fratboy because he felt like having a good drunken drive with a pretty woman. And the inevitable occurred.
