Not sure I agree, while visiting relatives in Texas a few years ago the road ways and access points seemed by be designed on a spur of the moment thing.
For example, while on the freeway you had to know to exit off to a side road about 2 miles before a right turn because the main connecting road into the town didn't have a direct freeway exit. It did have a freeway entrance though! So if you didn't turn 2 miles before, you drove another 5 miles down the road to the next exit, went over the freeway and drove about 1/4 mile then again exited on a side road because. . . you guessed it, no direct exit from the freeway.
In town was not much better, driving along the freeway I spot a Best Buy on the left just up ahead. How to get there. Well exit on the right, drive another 1 1/2 miles down a street next to the freeway, go under the freeway, drive 1 1/2 miles back down another street next to the other side of the freeway, and turn right. Mind you this was all in a pretty packed business district, so those side roads moved at a snails pace.
Then major freeway connections were just mind boggling. When one would join with another there would often be concrete barriers at least a mile out, so if you didn't pick the right lane you would wind up on the wrong freeway. The trouble is that you wouldn't see a sign until it was too late, well unless you had a car that could jump the concrete barriers that is. And of course to get back, you guessed it, go a few miles, exit on a side road, go a few more miles, cross over, then continue down another side road, merge with the freeway, and play the guess the right lane game all over again.
Still the best. While driving back on a 5 lane freeway traffic slowed down to a standstill for over an hour (*note the place we were was only about 45 minutes from the house we were staying at). During this whole inching forward everyone was doing (because of a two car accident mind you), the GPS system announces "Switching to pedestrian mode". I guess it thought we jumped out of the car and started walking (which to think of it might have been faster.)
Don't get me started on the weather, 11:30 at night trying to take a walk around the block, we needed a towel by the time we got back to the house.
