Using a 30-day month, that translates to $14/day for one car, which is more than my earlier estimate of $11-$22/day for two cars. And this car is used!
Again, the figure of people spending like 10-20% of their income on transportation is not uncommon these days. Such so-called fixed expenses disproportionately impact the poor, not to mention are ridiculous as a drain on the national economy. Having walkable/bikeable communities would drastically reduce such waste.
