Sai Lang (Full bet)

One of the strategies that caught my attention in the three kingdoms tvb drama series. =P

Given a situation as below:

There are two bullock carts moving towards each other in an opposite direction,

On a single narrow road above the cliff.

The one who step back consider lose.

But if both move forward, it will be life threatening.

If you are one of the bullock carts' driver, what will you do?
