I recently had Tesla install a dash camera in my Roadster. Driving in most major cities has become a constant near-accident experience and I have found it comforting to be recording what is in front of me if something were to go wrong. Has anyone considered a dash camera for their Model S and where it could be located? I would also love to see the back-up camera permanently being recorded on a looping-SD card. Then if the vehicle was ever rear-ended there would be good evidence of fault. These cameras and digital storage capabilities are not that expensive and could be invaluable in an accident investigation. I think some day all cars would have cameras (like now found in most police cars). After the dust settles next week on my Model S delivery, I hope to work with Tesla to see what they could mount and power around the rear view mirror to record what is happening in a wide field-of-view in front of the vehicle. Anyone have any comments or experiences with this technology?
