Why do we always drive on the "dirt roads"?

We are haeading off from Perth to Cape York this week. I am the one that nearly always ( have to be careful here) selects the route. So I showed my partner the route. 1st question. Why do we ALWAYS have to go on the dirt and that was only based on the section from Perth to Norseman via Hyden - Norseman road.

My response was the usual " we don't" followed by some quick justifications such as:

A. It's shorter - only valid if A to B distance is important
B. It's a good road - you only know after you've done it.
C. More to see - possibly true. See B.
D. Far less traffic than the bitumen - reasonable statement
E. Better camp sites - reasonable statement but see B.

Having mulled over the question for a few days I have come to the conclusion that all of the above are in fact mainly justifications. I like driving a lot. I choose the dirt because I like driving on it. It keeps me thinking, keeps me busy, keeps me challenged.

And you.

Why do you choose " the dirt" and

What explanation do you give for choosing so
