So Negitivefrags is probably right that the best top-down way to get this to happen is to place signage. But it's sort of fun to think of the best bottom-up way to get this to happen, assuming your local government isn't putting up signs.

For example, I love going a constant speed in start-stop traffic (letting gaps appear ahead of me then closing them as traffic stops) so as to smooth out the ride of everyone behind me.

So what's the optimal way to get this behavior to spread? It's probably not just to gun it to the front of the line and yell 'zipper!', everyone just thinks you're an asshole.

VikingCoder suggests "If you want to show people how it's done, you go the same speed as the cars next to you in the open lane, and zipper merge at the end." I love it, because it's really awkward, and people will note it enough to maybe think through what's happening, what your logic is.

But I dunno, maybe there's something else more clever out there, too.
