If you don't have to change lanes or just have to change few lanes when going from A to B, it is very easy for you because changing lanes are dangerous and not convenient.
When I look for a school for my children, I often take that into account.
Do we have a phrase to say the roads are very convenient for you to go because you don't have to changes lanes or many lanes?
For example, I have look for a right-roaded school for my children. (Like the way we say "right-handed").
