In 2000, the same London streets are congested with cars, and the average speed of travel in the inner city remains around ten miles per hour. We live with a new emissions threat: the global warming effect of carbon dioxide released into the atmosphere when fossil fuels like oil are burned.
We can only guess at the situation in 2100, but, if history repeats itself, our streets will still be crowded and the pace of travel relatively slow. The means of conveyance and the fuel used are likely to be completely different. As we enter this new century, it seems appropriate to address the changing context and developing contest for oil as the predominant transport fuel – in other words, to redefine oil.
