Could you read how the pressure is created? Around a sharp corner or such? When you're pulling by the front tires in the steering is unlocked it allows for turning movement. when you lock down the front you can see the steering wheel spinning back and forth when you go around corners. This allows the back tires to travel as they normally do. This is why you leave the car out of park at the very least so the steering wheel can turn freely allowing pivoting action.
Now if you're trying to drive your point about weight distribution fine do things the way you want to and I will give you the win on that one. No way you'll ever catch me doing it not on my life and certainly not on Dart freak 75's...
