Consider the fact that the car is set up for toe in while going forward.
Ever drive a rear wheel drive car with excessive toe out?

Very darty and unstable, and reluctant to stay in a straight line.

Sure, you may be able to get away with it, and it might make sense for a short haul, but towing is difficult and risky enough when you do it correctly, why add a significant amount of instability?
