It’s important to realise that the car is an extremely useful tool and for some it is vital to supporting much cherished independence. The problem is that we all too often fall into habitual use that is actually not the most convenient, cost effective or, environmentally favourable.
Even without considering the pollution that is attributable to private vehicles, the sheer numbers of them on the road on a daily basis leads to slow transit speeds, traffic jams, anxiety and short temper. Many of the vehicles used on a daily basis are used at a fraction of their potential capacity and make the journeys with only the driver. These are referred to as single occupancy vehicles (SOVs). By increasing the number of people in the car, we potentially reduce the number of cars making a journey. This reduces not only the pollution per person, but the levels of congestion.
