Perspectives Sharing Cars: The Future  of Road Transport by Oliver Brown

n most industrialized countries, households depend on personal vehicles for getting around. In the US, for example, there are two cars for every household.1 Society pays a high price for this inefficient system of transport in the form of pollution, congestion, and other societal costs. But in cities that are densely populated, where alternative transport options are available and where everyone is connected through the web, does it make sense for the majority of households to own a car? The emergence of new business models that facilitate carsharing and ridesourcing are leading many to ask themselves this question.

The Problem with Car Ownership The list of societal costs from road transport is long. They include the effect of carbon dioxide emissions on climate change, local air pollution, traffic congestion, road accidents, road damage, and noise pollution, to name a few. These costs are significant. For example, road transport accounts for more than a fifth of global carbon dioxide emissions from fossil fuels,2 making it a key contributor to global climate change. Road congestion is expected to cost Europe and the US a total of US$293 billion by 2030.3 But the prevailing ‘car ownership’ model of transport has a number of characteristics that make road transport more damaging than it need be. One such characteristic is the cost structure of car ownership over time.4 Owning a car involves large fixed costs, including the car purchase, registration, and insurance. However, the costs of using the car—the most visible of which is

fuel—are relatively low. Such a cost structure fails to provide a sufficient incentive for car owners to minimize driving and results in excessive car use, along with the associated societal costs. A second problematic feature of the car ownership model is the inefficiency of owned vehicles. Indeed, while most cars are designed to seat five individuals, the majority of trips in industrialized countries are completed without passengers.5 Low vehicle occupancy requires additional cars on the road, further contributing to excessive car use. Another factor contributing to the inefficiency of owned vehicles is the inability of the car ownership model to filter out old, fuel-inefficient vehicles. In a world where each household owns one or more vehicles, cars are only utilized during a small part of the day. Personal vehicles therefore depreciate slowly and are often driven decades after their year of manufacture. Consequently, too many old, fuel-inefficient cars continue to operate, further exacerbating the pollution impact of personal vehicles.

From Ownership to Access Improvements in technology are driving a shift in the way people access goods and services. The emerging ‘sharing economy’ is seeing businesses and households exploit advances in technology by renting out underutilized assets. This is providing an opportunity for the road transport sector to shift away from the existing model of car ownership towards a model of car access. Already, new business models like carsharing (short-term car hire) and ridesourcing (on-demand ride services) are providing low-cost alternatives to car ownership. These services can save many households money by avoiding the large upfront costs of owning a car, while providing a moderately higher cost per trip that incentivizes travellers to take public transport, cycle, or walk when possible. These business models also have the potential to improve the efficiency of vehicles. Carsharing achieves this by providing access to newer, more fuel-efficient cars, while ridesourcing has the potential to increase vehicle occupancy through carpooling.
