67% bicycle

car filled with fuel
car odometer: 27761 miles
bicycle odometer: 24359 kilometers
2009-09-19:
car re-filled with fuel
5.082 US gallons at $2.469, $12.55 total
car odometer: 28046 miles
bicycle odometer: 25276 kilometers
So, in 43 days, 285 miles (458 km) in the car and 570 miles (917 km) by bicycle. 67% bicycle.
56 miles/US gallon, 4.2 L/100km for the car alone, but if you add the bicycle distance in you get a notional 168 miles/US gallon or 1.4 L/100km. You'd have to add in the pizza and chocolate somehow to get a real number. 0.45 liters of gasoline a day at US prices is, well, pretty much a negligible cost. I do drive it a lot more in the winter, though.
Another thought: A very efficient car, left parked at home most days, averaged half a liter of fuel a day, which is, by American standards, pretty much nothing. Pour a half a liter of gasoline on the ground and set it on fire. OK, don't actually do that. But that would be a pretty darn good fire. You don't see the flames inside the engine, you don't even see the fuel, you just stick a hose in the side of the car now and then and see some numbers displayed on the pump. There is a lot of combustion going on in there, unseen. Great forces are commanded with a touch of that pedal on the right.
