Unfortunately not. The way the files are being written, there is a gap between when it closes one file and starts the next.
Technically, there is no reason for it to do it the way it does, but, that's how Tesla programmed it.
Your best bet would be to look on the drive and, assuming you haven't already driven more than an hour since the incident, see if you can look through the 1 hour rolling footage to see the vehicle if they had pulled in within the past hour, or, even if you had parked while they were already there and your recording may have their plate on it.
