Very early in the 80s, when I lived in Camarillo, CA and was getting my first exposure to cable TV, I remember some science fiction-ish action film. And I can't remember the title. It was something PG-rated, so it wasn't Mad Max or The Road Warrior, but it had a similar concept: it's hard to get gasoline in at least parts of the world. It had desert landscapes, car stunts, and explosions.
Here's the big thing about the film that I remember. There's a big city, bustling -- i.e. if this is a post-apocalyptic world, the apocalypse hasn't affected this city so much -- but there's a shot of a multi-lane freeway with, instead of cars, hundreds of people on bikes. I also remember the city had planes flying around it, so either gas was more available in this city or its use had been completely diverted to non-car use. (Though what happens in that future when that supply runs out was apparently a question that hadn't been answered yet.)
I've long forgotten the title of the film, but that freeway full of bikes, I've always remembered that. The film would've been circa 1980 or 1981. Again, probably PG-rated, because HBO played it during the day.
Anyone else remember it? Have I pureed two or more films together into a confused remembrance? (I've done that before. My memories of my first viewing of 2001: A Space Odyssey got mixed up with some other science fiction film. So I "remembered" the Discovery making noise in space and having windows all along its spine, and I "remembered" poor Frank Poole outside the ship, um, exploding. None of which was in Stanley Kubrick and Arthur C. Clarke's film.)
