I agree with Ultarc, get yourself a G1 Insight!
There's not a decent Insight out there that will get you less than 60-70 mpg on that commute. I average better than 60 mpg on the highway at 80 mph in mine. At 70 mph with a semi in front of me I average about 75-100 mpg.
Not that I envy your long drive, but if I had that 97% highway commute Ron Burgundy would be one of the highest mpg cars on the site (other than the plug-ins)
