Road maintenance is one area where I could see preventative maintenance taking off because once your road network gets to a certain size, there’s always maintenance that needs to be done. And then when it gets to a certain size after that, you’re always trying to be strategic with where repairs and upgrades are made because there’s not enough people or money to keep up. Plus, the rest of the network needs to handle the load when you need to shut down a stretch of road to do maintenance.

The benefits of this kind of preventative maintenance are too obvious for it to be dismissed like it is in other cases IMO.

Though on the other hand, this will lead to a situation that is even worse just like widening highways makes things worse, so I wouldn’t be too disappointed if they do end up opting to “save money” by not doing this.
