has gas price affected your life?  driving habits?  i know i try to drive 55 miles per hour, leave home 10 minutes early.  use less air conditioning etc.  still cost me $60 per week.

Turning A/C off won't save you gas, this is just a myth. Try to drive between 50 and 60. turn you cruise on. Get Honda or Toyota car.

I have changed my habits, such as driving around on weekends, drive to a C-store just to buy cig. etc........

Gas price is not $5 yet, why you are so much scared dude?

Crude oil is expected to reach $160/barrel by 15th July {means $160/159 ~$1.01 ltr ~ $2.5/gallon ~ $5/gallon (transportation+refining+pilferage + margin)}. Let's turn on the A/C till then. 

100% agreed with Bishal123. Turning the AC off doesn't improve a gas mileage. If you are driving a mid size car like Honda Civic or Toyota Corolla at 55-60 mph with A/C on, the mileage drops just by 1 miles /per gallon which is not a big deal. But it the A/C is turned off and windows are left open, mileage is severly affected as power is wasted to overcome the drag due to speedy air. It's better to get the engine oil changed in time,  tyre pressure checked ( don't let it go below 4 psi from the rated air pressure) and smoothly driven. Cheers.....
