I don’t drive an SUV. 
Um… I have a ULEV… Ultra Low Emission Vehicle heh and that is about all I can do at this point.
There is no reliable public transportation from where I live in the valley to where I work in santa monica. <shrug>
I parked the Jeep…sold the big Olds '88 (17mpg) bought a new Hyundai 35+ mpg (for my SO)…and I use the bike when I can. I’ve got an old '65 Ford pickup for work. Can’t do much about that, gotta haul stuff.(construction) But, I try to keep it (job locations)short though.
Plus, I won’t be mowing much this year…I just tilled everything but my immediate front yard and am planting a garden everywhere else. (reg. gas price in East Texas avg. $1.65 gal. this week)
Filled up the Hyundai the other day (10 gals.) had to make a trip…odom. showed 382 miles between fillups…
