Check out the new ‘petrol calculator’ on the right. It’s not quite right yet but when the database has been tweaked for litres you can use it to work out how much you save by cycling to work instead of driving. You need to know the price of petrol in your area and how many miles per gallon your car does.
The sidebar widget was created by Tim Grahl of CommuteByBike.com in the US. He’s got a ‘gas savings’ calculator on his site and I asked him, nicely, to produce one that featured litres, not gallons, and with the results in pounds sterling. Thanks, Tim, you’re a star!
