Ok.... went to visit a friend out of town this weekend (Tampa to Gainesville and back). Did all the usual stuff pre-trip (checking tire pressures, oil, etc.) and hit the road just before 9am.
The Interstate (I-75) was IMO a *little* less busy with traffic than it usually is on the weekend, but judging from the way everyone was driving they're sure not worried about the cost of the fuel they're burning. I put the cruise on 60 mph and since the weather was very nice I put all the windows down and opened the sunroof for the ride. During my two hour ride up there I passed 5 cars. Three of them were in a little convoy doing about 59 mph, and the other two were broken down on the side of the road. I lost count of all the large trucks and SUV's that passed me doing 70+ mph. On the ride back I passed 6 cars. Three of which were broken down... the other three were doing between 55 and 58 mph (obviously trying to conserve on gas like me). IMO obviously, for the people who can afford to travel the interstate at least, gas isn't expensive enough yet to make them change their driving habits. I got passed by at least 3 H2's on the way up that were all going well over 70 mph IMO.
Gas mileage details: 2005 Jeep Liberty 4x4 with 3.7L engine, stock Goodyear ST tires at 35 psi. All but about 40 miles of driving was highway mileage @ 60 mph with the windows down and AC turned off, with the balance being mostly stop and go in town driving, in Gainesville, with the AC on full blast.
318.3 miles total trip mileage on 13.244 gallons of gas = 24.033 mpg
Think people will start to change their driving habits when gas hits $4 per gallon?
