Will we all be driving EVs in ten years' time? Not without a Government conversion to ecological fanaticism, though EVs will probably continue to form part of some traffic management schemes. 'My guess,' says Roger Higman, senior transport campaigner at Friends of the Earth, 'is that people will think battery-power is not going anywhere. There will still be some hybrids around but the front runner for new cars looks like the fuel cell.' Most EV watchers agree. Ford, Toyota, Mercedes and others are well into development of this potentially zero-emission option, where electricity is produced from a reaction between hydrogen and oxygen. They're competing to have a model on the road by 2004.
