What kind of car will we be driving in 2010? Rather different from the type we know today, with the next 20 years bringing greater change than the past 50．The people who will be designing the models of tomorrow believe that environmental problems may well accelerate the pace of the car’s development. Today they are students on the transport design course at London’s Royal College of Art.
Their vision is of a machine with three wheels instead of four, electrically powered, environmentally clean, and able to drive itself along “intelligent” roads equipped with built-in power supplies. Future cars will pick up their fuel during long journeys from a power source built into the road, or store it in small quantities for travelling in the city.
Instead of today’s seating arrangements—two in front, two or three behind, all facing forward--- the 2010 car will have a versatile interior with adults and children in a family circle.
This view of the future car is based on a much more sophisticated road system, with strips built into motorways to supply power to vehicles passing along them, cars will not need drivers, because computers will provide safe driving control and route finding. All the driver will have to do is say where to go and the computer will do the rest. It will become impossible for cars to crash into one another. The technology already exists for the car to become a true automobile.
