i can tell you all that this will really help your every day driving. even if you are good at using the mirrors to judge distance and park, i am able to confidently back up while parallel parking to get very close to the car behind me. in the past i've bailed on many spots becase i was scared i'd back into the car. yesterday, while parallel parking, i backed up without looking at the camera, thinking 'hmm that looks pretty close' then i look down at the camera display, i had like 4 feet more room.
