Keep in mind that if you have a dashcam, if you're involved in an accident it may be a liability. The insurance company will surely subpoena the video and could quite possibly use it against you if there's any perceived issue with your involvement in any accident. You already almost surely have the black box recording the actual driving conditions before and during any accident, and more and more those are being subpoenaed in accident cases to determine liability. Big brother is already watching, but are you sure you want to give him that much help?
