Why so little? Well, people are always asking me "With such a cool modded car, why do always ride your bike and public transport?" I don't have a regular daily commute, so the car often doesn't get fired up for 2-3 weeks at a time. But once it does, it's a pleasure to know that how much less fuel I am using than anyone else on the road.
