Indeed 'tis!

I was looking through the rules and noticed that they say you have to follow the traffic laws in each country. This immediately brings up two points. First, will they be telling you in detail which things are different as you go through each country (many things are standard, but there are certainly a few oddities, use of passing lanes, stuff like that, to worry about, some of which might impact hypermiling techniques) or will you have to research them yourselves, and second, will the speed laws apply to non-Mpg Challenge racers? It is a race, after all. But the course isn't closed, so it might be impractical.
