I never thought this would be all that practical but I'm so glad I went for this option (http://gmauthority.com/blog/gm/general-motors-technology/gm-safety-technology/gm-active-safety-technology/gm-surround-vision-camera-technology/) While parallel parking yesterday I noticed that it gives you a very detailed view of how close your tires are to the curb. Now I can always park close to the curb without hitting it! 0 I've damaged so many rims in the past by rubbing them against curbs when trying to park. This feature is awesome! See how it works in the pic below...
