29 The average annual distance driven per car in the USA is about 18,000 km. If we assume an average speed of 50 km/h it means that in the USA cars are used 360 hours per year. A year has 8,760 hours so we drive our car less than 5% of the time. The rest of the time we have parked our car at home, nearby our work, a shopping area, the school, a restaurant, a car park, or somewhere else. For the world these figures will not be much different. So overall we use our car for driving only 5% of the time.
