One I'm particularly angry about is the deallocation of resources into keeping rail transport in favor of using trucks on nearly free highways.
Also, road wear scales with the fourth power of axle load. This means a 3-axle 30-tonne truck causes 15.000 times the wear of a 2-axle 2-tonne car. Even if highways are currently "nearly free" to maintain with a car-dominated traffic mix, moving all that rail transport into heavy trucks is going to rapidly make highway maintenance costs explode.
