alt Hacker NewsI looked up kerb cutting machines and it's interesting how much of the process is cutting through cast-in-place kerbs with special saws.
There are hardly any of these in the UK, for example, and kerbs are nearly always made of kerbstones that are sunk into the ground. They have their own problems with sinking when driven on, and I imagine frost heave in areas where the ground freezes seasonally. But it does mean that a dropped kerb installation is quite quick. Most dropped kerbs are simple tarmac ramps rather than concrete castings here.

I wonder if you could just ignore ignore settlement by provisioning for hydraulic slab jacking instead?
Include a built channel for injecting hydraulic grout a few months later once the settlements happened to correct it out.
The ones I saw didn't actually cut the curb - they had arms that held out the form and "built" them in place. I was surprised, as the still-recent but earlier curb cuts had very obvious examples of actual cuts. It was similar to this, perhaps https://www.curbmachines.com
