There was lots of chat about this on Caravan Talk a while back.
It appears that there are two schools of thought.
Accelerate out, or slow to remove the energy from the system.

I think the concensus was that few cars had the power to pull the rig straight. You really would need to accelerate drag style to pull it straight (like the weight at the front of an arrow).
Gentle slowing was the best bet for normal outfits, but neither option is guaranteed.

The best bet is to avoid the snake and careful weight distribution is the way to do this.
