A police officer cannot search your car under the presumption that you might be lying about something that might connect to a dash cam that might have been installed and running at the time of the accident that you might erase if he lets you go. Unless someone's died at the scene or was seriously injured or your appear to be engaging in some illicit activity like driving stoned, it's a pretty tenuous defense against your 4th amendment rights first to search your car, then seize your property. Not to mention the complications of the right not to incriminate yourself.
