It great you enjoy the game. If it’s by restructuring the road system, because it’s possible, great! It’s all about having fun.
I prefer to use the road-system as is: organical, and unefficient. When I need to build a road to connect A with B, I will again use the landscape and make it look natural: with bends and corners. And then use them to see my trucks and buses slingering over the mountains. That is my fun. 😉
