From nowhere to really nowhere

I've been meaning to post this for a while, Inquirer writer Inga Saffron's take on the lost allure for the outer suburbs. While she focuses primarily on one Philly-area region, she references Christopher B. Leinberger's death knell for exurbs.
Since I began this blog, I've spent a lot of tongue-in-cheek time pointing out the intersections around South Jersey where I live that have these curb cuts and crosswalks that lead to nowhere. But many of these locations would seem to be prime real estate for future development, so these curb cuts would seem to have the potential to become curb cuts to somewhere.
However, given what both Saffron and Leinberger write, that seems to be becoming less likely. We still have an oversupply of housing; surveys show baby boomers/empty nesters want do downsize and move into more walkable communities, and the younger generations need mobility to move where the jobs are.
I've said on other occasions that the concept of these curb cuts - to allow people with disabilities to move about more freely and without the impediment of curbs - is a noble one. No one wants to see anyone barred from where they need to go. But the blind following of government mandates that every new/reconfigured intersection include curb cuts remains mind-boggling. After all, I cannot imagine anyone, for instance, needing such easy access to get into the GEMS Superfund toxic waste site.
Death to the exurbs? Maybe too soon to tell, but undoubtedly, if it does come to pass, it will mean the birth of even more curb cuts to nowhere.
