Overview: A look at motoring in the year 2000 with William Woollard and Frank Page at the London Design Centre for the opening of the 'Drive Forward' exhibition. How will cars be powered in the 21st century? Electricity or hydrogen? Could towns and cities change to suit our motoring needs and one day will cars drive themselves? Also a special report from Paris on the lady designer who's created a car which changes colour to suit the weather.
