The Importance of a Mental Map

How far out would your mental map be accurate from your home as the center point five miles, 10 miles, 15? When would it start to break down? Do you think I thought about this in the way my mental map works is it works along roads. And so like if you go west from here along a certain highway, I can tell you what's on each side of the road the whole way. But sometimes I'm shocked because when I look at a map from the top down, the God's eye view, I see that that road is not straight. You lose except the compliment. Take the one where you get the nice compliment. Thank you.
