My spouse and I both ride motorcycles (50+ MPG). I've ridden for several years already (rain or shine). We bought another one a year ago, seeing this already coming when gas started up past $3.00 a gallon.
We have a high-mileage vehicle (45+ MPG).
We have changed our driving habits to combine trips more often.
We are vacationing closer to home.
No real change in food or goods and services we purchase, except that we don't go out as often to eat in restaurants, don't go to movies as often, and don't do as many activites as we used to that cost money.
We walk more often to places like the grocery store if we don't have many items to pick up.
We actually have lost some weight as a result of these changes, so it has had a hidden benefit.
I would say we're resigned to higher prices, but realize we can continue to do more to lower our footprint, so to speak.
Public transportation would be the next step if things were to continue in the current direction. Maybe a change in working hours and days (4 days per week instead of 5, if possible, to cut one more day of commuting to work in a week). If increased transportation costs for food continue to be added to food costs, it will become cheaper to buy local foods more often that are slightly higher in most cases. We've started a small garden with a few items, but that might expand quickly (I hate mowing weeds anyway...).
We have had the means to react and adjust, where others can't. And thankfully, neither of us has had a layoff.
