If you had a spool in the rear, I would agree with the statement about changing lanes but not with a sure grip or open differential. I've snapped axles-that weren't welded on by the way-while drag racing running slicks on a Duster with a sure grip and it just couldn't transfer enough torque to the unbroken axle to make the car turn. The engine reved and that's about it. I was able to drive it home from the track with one good axle by taking it nice and easy on the sure grip.
