I just got back from cornwall. I know there's lots of smaller roads, but is there a way to get columbus to route avoiding crazy minor road cut throughs? some of them i ignored as they were not advisable. I got the usual three options, but they were a bit unhelpful.

 

thanks,

Does the setting for the most efficient cut out the back doubles of taking the shortest route which is not always the quickest or most economic?
