I use the side view cameras every single time I park the car. I think it is one of the best additions they could have done to the car. When I pull the car into a parking spot, I turn the side view cameras on and move the car until the yellow lines on the display are in-line with either the markings on the ground or the edge of the curb. That leaves about 10+ inches of space between the front of the car and the actual markings/curb! It also helps you to make sure you parked the car nice and parallel... this only works on straight parking spots though, not on angled ones...

You can switch between the rear view camera and side view camera when you are in reverse by pushing the camera button... comes in handy sometimes in tight parking spots.
