That data should be possible to obtain, but there are some confounding factors—I can definitely imagine a family more inclined to drive than walk passing the factors that led to those preferences on to their children, for example. And I’m not sure how you’d control for that.
Most studies that try to separate genetic factors from “nurture” factors provided by the parents will twins that were adopted separately. It’s a small-ish subject pool though, and probably not recent since I don’t think they encourage separating siblings for adoption now.

Did they ever encourage it?
It definitely used to happen a lot, judging by the sample size in twin adoption studies (usually 200-something pairs of separated twins).
