Day 10 – how to save fuel?

We know that the most fuel efficient way of driving is to drive between 50 to 70 km per hour, which fits in nicely on most city roads’ speed limits. However it may not be practical and you will probably get a ticket for driving below the speed limit and thus blocking the traffic. May be just take the public transport if it is available (not possible for many), or plan your trip and drive less? How do you save fuel then?

Challenge: park your car a few inches away from your home.
