The arithmetic on that path is worth doing slowly. Three kilometers for $20 million works out to roughly $6.7 million per kilometer of walking and cycling surface [1], bolted onto a rail extension that arrived about ten years behind schedule [2]. Split among the thirteen people who spoke up for it, the ask cost about $1.5 million per advocate [2]. No rider chose that trade, and no rider was asked to.
The mechanism that produces such decisions is a funding one. Before the middle of the twentieth century, most transit was privately owned and pointed at one objective: fill seats, collect fares, hold down costs [6]. When governments took over the failing lines in the 1960s, the money started coming mostly from voters who did not ride [7]. Once the payer is not the user, the pitch has to be written in the payer's language, and the American Public Transit Association now sells transit as a route to work, education and healthcare that also delivers job creation, thinner traffic and cleaner air [8]. Each of the three levels of government writing checks can attach its own conditions, from Buy America sourcing rules and Davis-Bacon wage floors to state environmental review and local requirements on design, public art and hiring [9].
The California pilots are the cleanest test of what that stacking buys. Six programs funded by the California Air Resources Board, spanning electric carshare, bikeshare and microtransit in disadvantaged areas, were handed emissions, equity and vehicle-miles targets at once [10]. According to the Works in Progress essay's author, who studied them with co-authors, they moved poor people around competently: most users came from households earning under $25,000, and many trips were for work, school or medical appointments [11]. They also produced 128,880 net new vehicle miles and slightly more emissions, not less [12]. The goal that justified the appropriation failed. The goal nobody was funding is the one that worked.
Electrification shows the same bill in fleet form. Austin's CapMetro pays $917,000 for a 40-foot electric bus against $535,000 for diesel, a $382,000 premium of about 71 percent per vehicle [13][3]. Miami-Dade has spent roughly $1.1 million apiece [14], and replacement parts run dearer too [15]. Hold a procurement budget fixed at Austin's prices and it buys 58 electric buses for every 100 diesel ones [4]. Riders do not experience a bus's emissions profile. They experience whether a bus turns up.
The regulatory asymmetry compounds it. Buses account for under one percent of US transportation emissions and still operate under more rules than private cars, while road and parking construction stays comparatively focused on moving people [4][5]. And the people absorbing the delay have the fewest options: 91.5 percent of American households own a car, but only 45 percent of transit riders have one available at home [3]. Comparing those two populations is imperfect, but the gap is the point. About 55 percent of riders have no vehicle at home against 8.5 percent of households with no car at all, a rate roughly six and a half times higher [5].
That is the transferable lesson, and it is not confined to buses. Any system whose bill is paid by people who do not use it will accumulate the goals of the payers, because that is the only argument available for the next appropriation. The accumulation is not free, and the invoice does not go to the constituency that asked.
