Though your conclusion is probably still valid. maybe assume a two lane road (with the previously determined lane widths), and an average corner angle of 45 degrees (i'm pulling that out of the air, i bet a real average would be more like 20 degrees, but I have no data so 45 is as good a number as any) so outer to inner ratio is given by: pi/2*(r+12)/mpg -------------------------- pi/2*(r)/mpg ahhh, we see that the angle swept and the actual mpg do not matter, only the relative radi.
