We have that system already (at least, here in the Netherlands), where automated overhead signs urge you to decrease your speed in case of traffic jams.
In my experience, not a single person follows those signs. Everybody just keeps on going at full speed until they're forced to stop.
It would be a lot better (for everyone!) if cars were driven by machines that followed those rules properly.

Yup. Game theory exists for a reason, people doing public policy should think about its predictions.

People doing public policy not thinking about its predictions, is one of its predictions.
Just encourage people to use defensive behavior when they see a jam up ahead, and optimistic behavior as they leave the jam.
Sure, that's limited to people's line of sight (in the case of approaching the jam), but it's better than nothing.
Interestingly, I've been assuming both optimal behaviors intuitively. When I see a jam up ahead, I slow down well ahead of time, hoping that by slowing now, I'll avoid a full stop up ahead; similarly, as soon as I get out of the jam, I speed up quickly. Seems like the natural thing to do after a traffic delay.
