If roads were 20x wider I guarantee traffic would be reduced or damn near eliminated. They just want an excuse to charge people and/or enable the rich to get special transport privileges. Also where do they get off claiming these people are getting this for free? They bought it with their taxes, so to double charge them and exclude the poor is pretty messed up.

If roads were 20x wider, 68% of LA County would be streets.

Sure, turning two-thirds of a city into roads will cut down on traffic - but within realistic restraints on road construction, induced demand is real.

(There are 140mi^2 of roads now[0], and 4,058mi^2 of land mass[1].)

Well there is a hypothetical world in which you could stack roads. It's prohibitively expensive, but not physically impossible.
