Eh looking just at those numbers maybe, I'm kind of in an odd area the most direct way is via mostly slow residential streets. If I swing wide to the longer highway route it's 2 minutes faster but further (11 miles ~18 minutes) and more annoying dealing with traffic (where I merge onto 40 I have to get over 4 lanes in a short time) so I usually take the slower but more pleasant route.
It was far worse at my old apartment 5 miles in 11 minutes became 50 minutes if I took the bus.
I'm in RTP which is far from moribund but Durham where I live is getting the least new residents it seems.
Such a drive is likely not stable. 9 mile 10 minute drives, in rural areas, are stable. But unless your economy is moribund, once that's up to 20 minutes, chances are good that ten years from now that same drive will be 45 minutes.
