Male motorists are more likely to drive in a more environmentally friendly manner than females, according to the surprising results of a new survey. And more men than women say they will only use a car when cycling, public transport or walking are not an option. The new research, published today, also reveals that the rising cost of car ownership is forcing a new approach to mobility, with almost two-thirds (65 per cent) of UK drivers admitting that they have changed their motoring habits in light of the recession and rising fuel costs, and 30 per cent of motorists now only use their car for essential trips.
