If there's any mouse screen-scrolling it would look and feel terrible. The minimum target should be 60 fps and allow going higher if your system is capable.
There are many hills to die on, this is a very odd choice.
On later thought, this sort of rationalization is what might come out after determining the percentage of systems that can play at 60+ fps is so small that it's better to lower the bar for everyone and not make it seem like you failed to deliver.
I have no knowledge about this game, but I would suspect their core simulation loop running on the CPU would be the limiting factor, not the rendering on the GPU?
The background here is that CS2 has been reamed in reviews for terrible performance where it can't even sustain 30fps in many cases, even on high end machines. It appears Colossal Order has somehow not had regression testing or performance targets whilst developing the game and then got backed into a corner where they had to release anyway, resulting in a detailed sim that is too inefficient to be fully enjoyable.
I get where they're coming from. A large simulation where small elements such as cars are only moving slowly across the screen means that 30fps is probably fine, which allows them to add more detail etc.
But as you say, hopefully the game cursor and UI components are still snappy and responsive.
If you only have to perform calculations once every 30 seconds that could double your simulation capabilities. I bet the game is a pig performance wise. Paradox games tend to be super unoptimized

Recommended spec for those wondering.
I will probably look up the latest steam survey to see what percentage of people actually meet that. Keep in mind for anyone below this spec they are targeting sub 30 fps
