Well here gas has been holding at $2.99 and 9/10 so shall we say an even $3.00 a gallon? One station was $3.07 for awhile but dropped back to match the other 3 now.
How stupid can people really be though?? We have a station that went out of business here and there sign still has $1.37 posted 
Ya, you geussed, I see people whip into theat station every so often to try and get gas and wonder why the pump won't turn on. They looked confused then eventaully see the store is dark and empty. Well DUH, $1.37 do you expect them to stay in business long in todays market anyway at that price?? Happened alot more often when gas was only $2.20 but I have seen it at $3.00 a few times too.
I drive my kid to school because there is no bus near the house, the closest stop is out of the way so school is just as close. Just the dirt road itself is a 5 mile drive, then I get to pavement and maybe another 20 miles?? This in a F250 pickup and not much mpg there I think.
As for the speed thing, many people are stupid and tailgate to save gas themselfs. In auto racing it's ok and part of the game, but on open roads it's dangerous and stupid.
They get into your air stream just right and your car kinda sucks them along and has broken the main air resistance for them also. This is reffered to as "drafting". In auto racing it saves the second car gas and the added drag on the lead car causes it to use more gas as it sucks along the second car and has to break it's own air also. So in the last few laps it could make a difference rather a pit stop is needed for feul for the lead or second car and make or break a really close race. I get people doing that to me often. You can tell at times because they are 5' from my rear bumper at 60mph and when I slow to 55 or 50 mph they don't pass even though it's a clear wide open road, then when I speed up to 60mph again so do they still at 5' from the bumper. That is when I am glad I have realy good brakes 
I often give them a chance to pass several times and when they won't they end up crapping themselfs later. Funny how people will back off after the brakes smoke the tires quick. Now actually I am not being mean when I do that, they are endangering my saftey and life tailgaiting me like that not to mention the price of extra gas it causes me to use. At anytime around here a Deer can run out in front of you from nowhere. So far I never hit a deer myself but I have skidded to a stop 2' from them when they jump out of weeds and just stay there. NOT a good time for a tailgaiter and you never know when it will happen.
I see the idiots all the time too that pass on blind hills and blind turns, doing 65 in a 60 and they still gotta pass when it's not safe? Saw a couple hit the ditch to avoid a head-on collision too. Most of the time they get where they are going, about 30 seconds before I get there. Whoopdee doo!
Slower speeds may save gas but it's a trade off at times what is better. Hmmm 800 mile trip, do I want to spend more on gas and drive straight through non stop except for gas at 65-70, or do I want to save gas and drive 55 and have to spend money on a hotel and food on the trip? I do drive it straight through normally at the faster speeds easily, but when I drive it at 55 I do get tired and either get a hotel somewhere or nap an hour or two in the car somewhere.
On a 10 mile trip does it really matter? Most of the time is getting in and out of the car and walking to and from a building anyway.
