There are regular street grids, and there are street grids that are not so regular. An example of the latter:

Apparently 4th Street turns sharply northwestward from 6th Avenue, and eventually runs into 12th Street. Not neat, perhaps, but comprehensible from a map. Similarly, if not so dramatic, is the corner of NW 23rd Street and Meridian Avenue in Oklahoma City: crawling off to the southeast is NW 19th Street. This makes more sense in the grid context when (or if) you remember that 19th was a streetcar route back in the day.
Turn this premise several degrees, and you have the next scenario. The big blue dot represents 4900 Springdale Road, Austin, Texas:
This is, on first glance, perfectly sensible: were the grid extended this far east, 4900 would be about two blocks south of 51st. But Martin Luther King used to be 19th Street, and it’s practically on your doorstep: you can see segments of 16th and 12th, right where they’re supposed to be. From 4900 to 1200, it’s only a mile. But 1200 to 700 (at 7th Street, natch) is 1.8 miles, because the east Austin street grid is convoluted in such a way you almost wonder if those crazy New Yorkers had something to do with this.
For the record, I have bicycled the entire length of Springdale, which disappears into Manor Road near US 290, resumes on the far side of the freeway, and peters out into insignificance a couple miles farther north; I eventually threaded my way to Pflugerville, which in those halcyon days of 1970 had 550 people instead of its current 55,000.
