When a very important person has to get around, it can be a logistical nightmare.
Security is of the utmost importance, particularly for those who run a country, so it's no surprise that many leaders travel on the roads with a fleet of other cars keeping civilians at bay.
Barack Obama's motorcade involves dozens of cars cruising along closed roads as the man himself relaxes in 'The Beast', an armoured limo that's designed to act as a refuge in case of a chemical attack.
Japanese prime minister Shinzō Abe's fleet is a little more modest. Consisting of just five vehicles including his own Toyota Century, the vehicles travel on open roads with other traffic.
To make sure civilians keep their distance and the prime minister's car keeps moving, staff wearing white gloves hang out of car windows to direct traffic. It's an elegantly efficient solution that's fascinating to see in action.
