You're comparing the cost of only self driving tech vs the cost of the entire rail infrastructure. • Underground parking for 600 cars? 35 million euro - https://youtu.be/mXLqrMljdfU?t=690 https://youtu.be/mXLqrMljdfU?t=690 • Rebuilding a highway? Half of the transportation budget gone - https://youtu.be/SfZYB-rnejk?t=479 https://youtu.be/SfZYB-rnejk?t=479 • Adding just one more lane bro to a freeway? $2.2 billion - https://youtu.be/uxykI30fS54?t=840 https://youtu.be/uxykI30fS54?t=840 Take into account the money saved from scaling back car infrastructure: • lower obvious direct building and maintenance costs • reduced healthcare spending - increased activity levels [1], lower local pollution [2] • lower stress thanks to reduced noise levels • less of a need to spend money on counteracting the negative effects of climate change • freeing up a significant chunk of the valuable ~30% of space in cities taken up by oversized roads and parking lots -> more housing, denser cities -> less travel needed -> lower costs Sum all that up and then tell me self-driving is cheaper than rail.

[2]: "Each year air pollution causes thousands of Londoners to die prematurely and is associated with an increased risk of Londoners developing life-changing illnesses like cancer, lung disease, dementia and asthma. [...] So far, the ULEZ has contributed to over 1 million hospital admissions averted by 2050."
