What is your EPA estimate? Mine is 374 I believe. 450 is no problem, but I often find it not convenient to get that close...
Especially when fuel was 3.40 at 200 miles. 3.60 at 400, and then 3.90 when I peaked 400! Patience did not pay off. It collected on me.
I thought I read the whole thread, and disn't see that. But I honestly would rather travel alone or with my wife/friends. I am okay with meeting people over the internet, like this, but I'm a bit careful in some aspects. Plus, ya'll would drop my mileage.
