I also find the idea of what your preference would be in counterfactual universes a little hard to grasp.
A lot of the responses said things about how if the train system near them were faster, more frequent, more convenient, etc. they would prefer it.
It is a strange kind of discussion.
We could come up with counterfactuals on any mode of transportation that would eventually make it preferred.
Why would it be worthwhile to talk about preferences for imaginary transportation systems, then?
