TomTom estimates how much time a commuter loses to rush-hour traffic across a year.

• The figure is annual hours lost during rush-hour commuting.
• TomTom models a 10 km trip twice a day on working days.
• The city photo is only a clue. The answer is the annual time penalty.

A high number does not simply mean slow streets; it means rush hour adds a large penalty compared with freer-flowing travel.
