Can't get better than 33-35 mpg.

No, I'll cause some accidents.

That's why you drive on the slower outside lane instead of the inside fast lane....that's what I do when I go 90 km/h on the highway (speed limit 100 km/h = 60 mph) except I move my seat all the way forward with my face close to the windshield and hands at 10 - 2 on the steering wheel for the full annoying effect when others pass me.
