I think the reason why no one really sees them on cross country trips is simply from the fact that its not really used as a road trip vehicle by the bulk of the owners.

If you drive around an urban area, during rush hours, and lunch hour, you will most likely see a couple heading to and from work. If your traveling across Kansas at 10am on a Sunday morning, you most likely aren't going to see any.

Here in Colorado, I've been seeing a lot of Crossfires in North Boulder, and through Westminster/Arvada. Unfortunately, Bat's hasn't been one of them for the past 3+ weeks. (sigh).

Its all time and location related.
