With the HD backup camera, parking sensors are not necessary on the rear of the Model S. But the front is another story, and that's where, without sensors, the bumper is most vulnerable to damage. I should know -- it's where I've scraped several of my car's front bumpers.
For the past several days I've been searching for a front sensor system that will not require drilling holes in the bumper. I finally found one this morning. It appears to have been developed for the UK market. The "sensor" is a metallic tape strip that lines the interior of the front bumper from side to side. It will require removal of the front bumper for installation, but that's usually not too difficult.
I'll order a set soon and have it installed on my S when it arrives.
