With landers, rovers, helicopters, Ubers, etc., rapidly accumulating on the surface of Mars, NASA has announced plans to launch the first extraterrestrial robot traffic cop in July of 2023. The proposed Primary Automated Traffic Regulation and Ordering Lander will have the tools necessary to enforce right-side-of-the-road driving, a speed limit of 50 km/h, and four-way stops at all unmarked intersections. The Japan Aerospace Exploration Agency has already announced plans for a competing lander to enforce left-side-of-the-road driving.
