Went for Kalganids, because I didn't want the currency name to refer to any existing country or currency. Of course, I would have preferred the Euro, because then I wouldn't need to worry about currency exchange and could just use whatever I already have in my wallet :D But still, Kalganid sounds fair enough. I guess it's referring to Asimov's books and not to the Chinese or Australian areas :)

Why does this make me think of telescopes and skirts?

Which option should I choose if I reside on a continent where public transportation is a viable alternative to owning a car and do not possess a driver's license?

Commander Keen 1 somewhere in c:\old_d\old_c\old_f\old_d\old_g has files dated to 1990. Given an infinite amount of time (the interval for changing hard disks being a good measurement unit, BTW), this chain of old_somethings will grow infinitely long.
