Many printed US maps emphasize divided highways (often including 
undivided multilane highways). Perhaps a thicker line style at low zooms 
where lanes>=4 or oneway=yes -lanes=1.

A separate color for toll=yes (like MapQuest does, but also for toll 

Fix bloody Georgia and the way the trunks (and other highways) blend 
into the trees.

Render shields at lower resolutions, since the US is not as dense as the UK.

De-emphasize railways at lower zooms.

Label motorways with both name and number where both are tagged (this 
would be useful even in Europe).

I'm not sure what the point of this would be - there's definitely enough 
variation in importance for all these classifications to be useful.

Canada and the US have rather similar road systems, so what works in one 
should be good for the other. I believe Mexico has a fair number of 
rural non-motorway toll roads.
