> In what place is this 30 minute drive from a rural area to the urban center an actual thing?
Where is it not a thing around any major centre? Every city is ultimately going to have rural area outside of it. I suppose you can find some city that has poor geography or ridiculous suburban sprawl that impede access. There are always outliers. But in general?
Of course there are also rural areas further away, and maybe if you were trying to work in some kind of local industry (mining, agriculture, etc.) you'd need to be further away, but since we're just talking about WFH...
> There's not some abundance of rural areas
How many do you need, exactly?
