Like in all big cities there are many traffic jams in Paris (we call them "embouteillages" in French - or bottlenecks in English). Paris is not the worst though, according to Inrix (an American company specializing in traffic monitor worldwide), it is the 8th most congested city in Europe. In 2013, Parisians wasted no less than 55 hours in their cars... I took this photo in the tunnel than runs under le Louvre gardens.
