Any other place doesn't have the literal geographic barriers to construction that the Bay Area does, or Prop 13 distorting housing incentives. For instance, Atlanta can absorb tons of new people moving in (which they are!) and there's infinite space to build out in all directions in the suburbs there.
Of course everyone will still end up stuck in traffic.
Hence why building suburban sprawl is unsustainable, and is actually a major economic problem for the Bay Area & most of the US. Eventually you end up like Detroit, since suburban sprawl is very expensive to maintain.
Urban areas need to densify rapidly if we hope to avoid financial catastrophe in the US, and many areas need to be returned to agricultural use instead of suburban sprawl, as with sprawl we have essentially covered our most fertile land in low density, high maintenance housing & support infrastructure.
