I typically drive with a dashcam. Am I allowed to videotape (dashcam) when entering Mexico from the US by car, or must I stop my dashcam?
If I must stop my dashcam, what's the latest point when I need to stop the dashcam? (at the exact border, when the Mexican Customs and Border Protection facilities become visible, when the first Mexican agent becomes visible, when a Mexican agent asks me to stop it, etc.)
