OK, perhaps not lazy, but lets just say you don't need to be as careful with the lines you take.
It certainly makes the tracks you would have driven previously easier to tackle, which also translates to easier on the JK and easier on the tracks as well (see I was paying attention!), so yes, safer.
Just to play devils advocate though it also gives you a little more confidence to drive more difficult tracks that you wouldn't have previously attempted and get yourself even deeper into trouble if you're not careful.
