I like this idea a lot. What is involved in getting "certified" (or whatever) to satisfy the (I assume) Court's requirements?
What does "maaaan were they busy" mean, exactly? Would you have time, for instance, to go to lunch or would Sunday be your only day "off"? (If even that.)
Other than that, no inventory to worry about and I suppose you would make them use their own car for any "behind the wheel" stuff... what more could you ask for?
