Hypermiling

7 days until payday:
Despite subsisting on leftovers and oily but inexpensive canteen food, a budget deficit is developing. It's hard to plan for those extra little expenses, like handing over the contents of the wallet to a jovial policeman after performing an illegal U-turn (last night).
Then there's filling up the petrol tank with what might as well be Chanel No 5, going by the price.

However, this evening I learned a useful tip from a very old episode of Top Gear that helps to maximise fuel economy. From student days, I developed the habit of putting the car into neutral at the crest of any incline in the road and coasting down. But it seems that in neutral the engine still uses a small amount of petrol to keep itself from stalling. What you have to do is coast along while still in gear, and absolutely no petrol is used. It works! Tried it out this evening.

I draw the line at Drafting though: A “deliberate form of forced tailgating,” this involves turning off your car’s engine and then following closely behind the vehicle in front of you “in order to take advantage of the reduced wind resistance in [the other car's] immediate wake.”
