According to Apple’s cell phone tracking data, driving automobiles in the United States is down from normal by about 1/3. [Note: See line 148 of the underlying spreadsheet.]
As a result of this one-third reduction, U.S. freeways and streets are now, in the experience of your humble DbC editor, operating roughly like they are supposed to operate. Traffic jams have become truly rare, and travel times pretty reliably approximate what distances and speed limits together suggest they should.
The obvious conclusion from this natural-experimental result is that our existing automobile facilities are under-built by some factor that explains all the headaches and waste of normal automobile travel. That factor has to be at least 1/3 — and might be higher, since there are probably issues of greater-than-1:1 scaling in the infrastructures that would have to exist in order to allow the now-missing 1/3 of normal automobile traffic to enjoy the optimal results now occurring in these abnormal, reduced-use conditions.
So, in order to allow today’s stock of automobiles to work as advertised, we would need to have about twice as much roadway capacity as we now do.
Likewise, if we were to try to sustain this level of functionality, all future accommodation of still-more automobiles (i.e. the normal plan and assumption) would have to be roughly twice as big as we are accustomed to such projects being.
The fact that we don’t (and won’t, and could not) provide such accommodation speaks not just to the material and geo-spatial insanity of cars-first transportation, but also to the gargantuan time-theft that inheres in it, under corporate capitalist normalcy — something, btw, that our overclass is positively quivering to reopen/re-impose.
