Explain Me Parktronic, Please?!
85mm is right...I think you'd be way beyond your comfort zone if you pulled up behind a car in traffic and the parktronic alarm went off.
I've become quite dependent upon this gizmo and I had a sensor fail in the rear bumper & didn't realize it. I was parking the GL and got very close to a post thinking, "Gee, the alarm should have gone off." I parked & got out to look. Sure enough, you could have slipped a piece of paper between the bumper & the post, but that was about it. I had a sensor failure in the rear bumper & the system was deactivated. I didn't notice the Parktronic light on the center console was on (hard to see in the daylight) which means that Parktronic is off. Got the sensor fixed & all is good, but I'm not as dependent upon it as I was before.
Never become too dependent on anything like this, it's purely technology and only there to assist, not to make the decision for you.
I use the orbital on all my cars for polishing and waxing with excellent results thus far. Saves alot of time and elbow grease. No swirl marks evident either which is always a concern with these devices.
