This weird Twitter thread began Friday in which Tesla CEO and unrepentant over-tweeter Elon Musk started arguing about whether trains or cars belong in tunnels.
BART picked a fight with Musk after seeing him tweeting about the virtues of tunnels, and asserting, oddly, that trains don't belong in them, they belong above ground.
Possibly using part of a campaign to boost ridership, BART responded by tweeted a diagram showing how twice as many people per hour can cross the Bay on its trains as can travel over the Bay Bridge in cars. Musk took these as fighting words, because of his beloved Boring Company project which proposes that we can solve all our traffic problems by putting superhighways underground.
Shockingly, Musk didn't really engage with BART after they started responding.

Another great thing about many layers of interconnected tunnels with ramps & elevators is that they can go from near your home all way to popping up at destination parking lot— Elon Musk (@elonmusk) May 24, 2019
Thus *reducing* existing road traffic— Elon Musk (@elonmusk) May 24, 2019
Tunnels are great things to run trains through. Not cars.— Kieran Jones (@quayran) May 24, 2019
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— Elon Musk (@elonmusk) May 24, 2019
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? https://t.co/2Hu3uzu2ND— SFBART (@SFBART) May 25, 2019
Here it is. We also run on 💯 electricity. pic.twitter.com/leK1mLzcrc— SFBART (@SFBART) May 25, 2019
In other news, Elon Musk spends too much time on Twitter, and his tweets have caused Tesla's stock to sink multiple times.
