I've looked for this movie/series on streaming services for years without luck. Here's what I remember:
In color, English seemed to be original language.
I think I saw it late at night on a local PBS station, probably in the 1970s or later.
At some point, I think just before the movie starts, at least one EMP has been detonated. So, "modern" vehicles don't work in the affected area, but older pickup trucks without electronic ignitions still work.
For some reason, I don't remember it being a post-apocalyptic movie like Mad Max. There's still some civilization.
I think the initial scenes were set in a semi-desert area with hills, and for some reason I think it might have been in Australia or New Zealand (although I don't remember accents).
One scene I remember vividly: Two people are standing in the lobby of a hotel. One of them has a handheld box that functions as a wireless search engine. While the search is underway, a male voice says "I'm searching, I'm searching" while a bear juggles balls. I think why I remember this is because I watched the movie before iPhones were a thing.
I think there's a scene related to a space station (but I may be confusing this with Contact).
