The Worst Cities In the World for Driving

• Manila — Triple-lane changes, using opposite lanes to escape jams, and an aversion to signaling
• Seoul — Public transit vehicles can legally ignore traffic signals, and scooters take to any patch of pavement
• Beijing — Over three million vehicles on the road, with lane markings and traffic signs widely ignored
• Mumbai — Cars overtake on blind corners, accelerate off side streets without looking, and share roads with roaming animals
• Ulan Bator — Only a quarter of roads are paved, and country roads outside the city are barely maintained

• Rome — Tailgating is a national pastime, rearview mirrors are accessories, and dozens of collisions occur daily
• Athens — A general disregard for traffic laws results in streets blocked by double- and triple-parked vehicles
• Paris — Narrow streets and the Arc de Triomphe roundabout with roughly 13 entrances, no markings, and no lines
• Toronto — Home to North America's busiest highway (the 401), with up to half a million daily travelers
• Orlando — Theme park traffic creates bottlenecks and congestion that frustrate even patient drivers

Research local driving customs before renting a car in any unfamiliar city. Understand the rules of the road, expect the unexpected, and consider whether public transit might be a better option. If you do drive, leave extra space, drive defensively, and always carry your rental agreement and insurance documents.
