Two cars head toward each other.
The first driver to swerve loses the game, along with some stature among his adolescent peers.
On the other hand, if neither driver bails out, both lose in a bigger way.
What to do?
Toss your steering wheel out the window in full view of the other driver.
Once convinced that you’re irrevocably committed to your course, he will, if rational, do the swerving himself.
