>E.g. a quick search finds claims [2] that average US households are paying $250 in gas per month (-> 3k per year). Here are un-avaoidable things you are overlooking, at least for passenger vehicles people own/lease: * Depreciation (with very few exceptions) * Insurance * Routine maintenance (brakes, tires, wipers, filters, oil, transmission fluid, coolant) and cleaning. Even on electric cars you have still have most of those. * Parking (where applicable) * Inspection (where applicable, minor) * Registration (minor) Transportation is very consistently a Top 5 expense for a given household, and for many households, Top 3. For people who go through cars like toothbrushes, usually second only to housing. ----- For those taking commuter rail, pass costs are a lot higher based on zones. In most markets, Zone 1 and Zone 2 isn't the most common users, but Zones 3 and further out. That puts costs substantially higher than BART or MUNI, and will usually be a portion (not complete) transportation costs. If you are able to take a metro system exclusively, you're fundamentally paying part of that cost through higher housing costs (not doing so is an exception). Not something that may be directly attributable as "transportation cost", but the increase is there and very material in terms of higher housing costs.
