Thunderf00t slams it again: Elon Musk LITERALLY reinvents the tunnel! - YouTube

That video includes some clips from a 2015 promo video for the Hyperloop. At 4:28 one finds that promo video's clam of a total LA-SF cost of only $6 billion, about $10 million/mile. I don't see how that can be taken seriously.

BART picks a fight with Elon Musk on Twitter over tunnels - SFGate

It started when Elon Musk tweeted a link to a Boring Company FAQ page: "Boring Company guide to why tunnels are awesome & safest place to be in an earthquake."

Someone tweeted in response "Tunnels are great things to run trains through. Not cars."

EM responded "Opposite is true: you can have 100's of layers of tunnels, but only one layer on surface (to first approximation), therefore trains should be on surface, cars below"

BART's official Twitter account responded "We carry 28,000 people per hour through our Transbay Tube under the bay because of the capacity of a train. That's nearly twice as much as cars over the bay. Why wouldn't you prioritize something that carries far more (and safely with automatic train control) over cars?"

I love the BART Twitter and transit Twitter in general. The BART social media team just doesn’t give a (hoot) and are willing to tell it like it is - “delay” becomes “a collision with a person”. They also make sure Elon Musk doesn’t get to claim a tunnel is better for any one mode of transportation - especially one with a habit of meltdowns and fire regardless of that car’s power source.
