Are the patterns of car travel di erent from those of general human mobility? Based on a unique dataset consisting of the GPS tra- jectories of 10 million travels accomplished by 150,000 cars in Italy, we investigate how known mobility models apply to car travels, and illus- trate novel analytical ndings. We also assess to what extent the sample in our dataset is representative of the overall car mobility, and discover how to build an extremely accurate model that, given our GPS data, estimates the real trac values as measured by road sensors.
