A survey by Denmark's road directorate shows that more than 40% of motorists use their cars instead of walking or cycling even for journeys under two kilometres, Jyllands-Posten newspaper reports. For slightly longer trips, 4-5 km, the proportion rose to just under 60%. Cars have 70-200% higher fuel consumption for the first kilometre of cold-start journeys, writes the paper, noting that cars fitted with catalysts must drive for more than 3km for optimal efficiency.
