If the argument is that walking them is not fun, then yes that is true. But, those streets are no different than any other street in DFW in size, etc. The constant beat to have walkable streets in DFW is never going to happen like a New York or Chicago environment. The local elected leaders will make sure of that. I am not opposed to it happening either, but knowing the realities needs to also be recognized as well.
I try my best to avoid that part of town. I have been to a few restaurants there and finding parking is very frustrating and time consuming. Otherwise you have to fork over money for a valet - and maybe this is just an individual peculiarity but I have a thing against giving my keys to my vehicle to some random stranger.
A friend of mine pointed out the problem with that part of town: In terms of congestion, traffic, difficulty finding parking and the overall hassle factor of getting around, it is almost as bad as driving in a northeastern city. But, unlike northeastern cities, if you live or work in uptown Dallas, for all intents and purposes, you are likely as car dependent as you would be if you lived in Plano or McKinney. So, basically, you have the disadvantages of urban and suburban and none of the advantages of either in terms of mobility and ease of taking care of errands and such.
The area is acquiring a density that overwhelms its century plus old infrastructure. The road grid in that part of town was laid out in the late 19th and early 20th century and was primarily residential/suburban. Most of the streets were lined with two story single family homes with large yards. The street grid was simply not designed to accommodate the traffic brought about by current density. And, while the area is very attractive for walking, it is not walkable in any practical sense unless one happens to work and live nearby or wants to be able to walk to a not-so inexpensive restaurant or bar. My understanding is that a Whole Foods is going to be built somewhere in that part of town - so that might help. But I think it would be many, many years - if ever - before it could become walkable in the way that New York City or Boston is.
So I think it will likely continue to be a part of town that is very attractive but a big hassle in terms of actually getting around and doing anything. I enjoy driving through and being amazed at just how much it has grown and prospered since I was a kid. But I think it would be a very frustrating - not to mention very expensive - place to live or work.
