Traffic jam near Airolo, Switzerland

How would you like to wait over two hours in this traffic jam in Switzerland? As the road sign in the photo confirms, this is the highway from Lugano to the south to Luzern and Zürich in the north, shortly before it enters the Gotthard Tunnel. The tunnel has only one lane in each direction and the highway has two, so in summer the queues stretch for 15km (10 miles) as motorists try to ‘merge like a zip’.
