Good Grief.... Hypermiling.... urgh.... just drive the car people and be sensible......
That extra 10 cents you save per gallon worth of mileage is not going to improve your retirement portfolio..... find some other means.....
In NJ you will likely get in to or cause an accident driving like a noodle trying to save a penny.....
If you need to save money that badly get a moped or a bicycle....
Hmmmmm...... do you control what you eat to such a degree to save money on food and reduce trips to the pisser
Wanna save money - stop buying coffee on the way to work; make it at home; if you need to buy it go to McD's or 7-11 instead of Starbucks or Dunkin Donuts
Don't buy a cd for one song.....
Don't spend a s*** load on a car stereo and dvd players and crap.....
Don't spend $2000 on pointless rims - all wheels go round the same and look the same at anything above 25 mph anyway.....
Cancel Cable/Satelite.....
Drink tap water instead of bottled water......
Don't drive 3 miles to a store and such... try walking, God blessed you with legs (sorry to those who may not have any

)
Point is thousands of econmising can be done without foolish driving
Sorry for the negativity.... I must need a Starbucks, guess I could drive to the one 2 miles from my work
Cheers
