>>1788808Hi there, OP here.
I'm actually from the US. Fun fact about all the road/highway grass stuff, that's usually handled by the local county officially, and contracted out to local farmers for next to (or literally) nothing in reality. Farmers get to keep the grass clippings for silage, and may or may not get a small stipend from the local government. County and state parks really only mow an insignificant portion of the acreage of public land in their localities, because small towns/counties only have a small number of parks crews, and states have theirs spread among multiple public use land areas.
But I must admit, the landscaping expenses for just good old fashioned grass aren't wild, and may even be comparable to regularly replacing pavers as they get worn out. More and more I'm not seeing downsides to grass tramways.
>>1788821Keeping grass short also helps get rid of water faster, which is good for infrastructure.
