I actually wrote a program to generate all permutations of both Bob and Alice's first choice, whether they will switch or not depending on all permutations of what the outcome of the first choice is, in all permutations of {car, goat, key}. Fortunately for the other puzzlers, the program didn't work, and I was unable to debug it.
