I have no shift into 4wd on the fly in my trucks. But I have driven hwy speeds on snow in 4wd Hi. The snow allows for wheel slip, and differant wheel speeds for turning. I wouldn't do that on dry pavement however. Another factor is most trucks don't have locking diffs in the front axle. With a locker in the rear and 4wd, 3 wheels are actually driven. That allows the other front wheel to act independently.
