If you are using your roads to do gps pathfinding, then you are indeed doing it wrong. Do not do in infrastructure what can be done in code. You can't version control your infrastructure, but you can version control your code.

And with cloud instances and VMs providing abstractions that don't map 1:1 to the hardware they're running on, all your infrastructure becomes code to create reproducible deployments, or serverless execution.

You don't build your roads immediately before you start driving, and destroy them after you're done, and build only as many miles of road as you need each time you go for a ride. They're not a great analogy to what we do with computers.
