sry i dont imagin seattle traffic is anything like iowa. there arent big freeways around where i live. its mostly 2 lane roads with some painted stripes in the middle to keep u from having a head on collision and gravel. some roads are just dirt.
i drive with with great vengeance and furious anger. the same speed no matter the road or weather. in fact going fast in deep snow seems to work really well. as long as u dont mind the steering wheel being more of a suggestion wheel.
so glad we dont have points in iowa. also there are never speed traps if u stick to gravel.
