If a vehicle is approaching from the right at 30 mph (45 feet per second), you will need a gap of at least feet to safely cross the intersection. When turning right into 30 mph traffic, you need a gap of at least seconds to complete the turn and establish space around your vehicle.
Given that the signal will travel at the speed of light, we can work out the time depending on the distance between Mars & Earth (obviously varying as the two planets orbit the sun). Note that to receive and send back data to a rover, you need to account for a round trip - worst case around 45 minutes. Also, the Earth will not always be visible from every point on Mars (the earth could be behind the horizon), so a large amount of there won't be line-of-sight at all.
