What to do with an out of date piece of satire?

A few years ago, I started working on a script that was in some ways a send-up of The Fast and the Furious. It was mostly for fun as I didn't think it would have much of a chance at getting made into a movie. Recently now that I've tried to do some writing that I do intend to publish, I've taken another look at it.

Well, there's a problem. The script was not just a movie parody but a spoof of car culture. Many of the attitudes and ideas that the script poked fun at have changed. The tension between people who race American and Japanese cars, which helped drive the story, is not at the same level it was then. And so forth. Bottom line is, I think this script has a pretty good chance of being too dated to make fun of the current scene, and I suspect trends may change so much in the time it takes to shoot a movie that just updating it won't do.

So I've got a question: What do you do if you find you've written a comedy that depends too much on current trends? Any thoughts on how to make something more timeless?

Thanks for the encouragement. I'll see if I can freshen it up a little (I already made a few changes, making it more sympathetic to some of the major comic characters) and get a complete script.

Thanks. I'll have to give this some thought. I may just wind up recycling some of its better gags into a new script that is less time-dependant. I think some of the best gags are ones I could reuse for a new and better storyline, anyway.
