Re:Speak a language they can understand
Tesla owners are scared of guns. They would cry if they saw one.
They seem pretty fond of flamethrowers though.

Re:OSHA violation of the day
Of course, these tunnels are blatant violations of all tunnel safety regulations: They don't comply with railroad tunnel safety requirements, highway tunnel safety requirements, or even the most lax of mine safety requirements.
There are no Federal train tunnel safety requirements whatsoever. The Federal Railroad Administration "determined that regulating bridge or tunnel structural conditions or requiring inspections would not be cost-effective to FRA when considering the cost of implementation and enforcement."[Page 22] What little Federal oversight of railroad bridges and tunnels exists happens only as part of track inspection, and there is no Federal standard to which those inspectors work.[Page 23]
There are no Federal highway tunnel safety requirements either. The only thing that exists are preliminary recommendations from the NTSB and a committee to conduct research about the possibility of issuing guidelines from a group of state departments of transportation representatives, the American Association of State Highway and Transportation Officials T-20 Tunnels committee. Neither of those existed before the ceiling collapse in the I-90 connector tunnel in Boston in 2006.
What voluntary, industry association guidelines exist are intended to deal with designs where internal combustion engines are allowed to operate inside them and, in the case of highways, where every vehicle uses its own independent steering to navigate the tunnel. Neither is the case in a Boring Company tunnel. Boring Company tunnels are effectively subway tunnels. The New York City subway system tunnels are just 18 feet high at the center, less at the edges. Boring Company tunnels are 14 feet high. You're telling me that 4 foot difference is the difference between life and death? I call bullshit. Whether or not you can walk out of a 14 foot tunnel in the event of a fire depends entirely on the ventilation system and fire safety systems in the tunnel. There is no public information whatsoever about what those systems may be in Boring Company tunnels, so no conclusion is possible at this time.
Stop blathering about things you know nothing about.

Re:Running the numbers
The simple answer is, that it will depend on how smart a builder is.
If they look far enough ahead, then they make it trivial to connect multiple systems into 1. -
Re:Shills for big oil abound...
Dude, you are a lying piece of shit and a shill for... trains? How cute.
Charge/discharge efficiency of typical consumer lithium-ion batteries is between 80% and 90% efficient." In your language, that's a loss of between 10% and 20%. Definitely not "over 30% loss".
Fuel cells are worse, much worse, with a typical real-world efficiency of around 45%.
Trains (electric, diesel, or coal/steam, all the same) are a _great_ way to get around. And wait. At every. fucking. stop. across. town.

He has been lucky...
...if he worked for Elon Musk, being fired by a machine could be a very painful thing.

Re:Is it reinforced?
Yes, but the very low shear forces make this less of a problem.
They talk about it in their FAQ.

Re:That was fast!
Look at how small it is. A typical subway train tunnel is triple that diameter.
That's one of the ways they are speeding up construction. The amount of material that needs to be removed increases by the square of the diameter.
Getting in and out will be stepping down into it and sitting only while the carriage roof doubles as the door. Which I guess means the real question is how it will be ADA compliant.
Getting in and out of the "skate" will be done on the surface, where there is more room. I'm more concerned with emergency exits.

Re:How about fire?
I'm pretty sure fire kills bacteria, so how about flamethrowers? (Predictably, Elon is ahead of the curve on this.)
Fire is a hell of a drug

Re:ho boy, a redundant system at 10x the cost
I have trouble understanding what you're even picturing that the system is. Perhaps you should read the FAQ.

You all need to read the FAQ from the Boring Compa
For all of the people out there who have concerns about the Boring Company and tunnels they are planning to build, you really need to read the Boring Company FAQ.
Worried about earthquakes? They talk about it.
Wondering what the heck an electric skate is exactly? They talk about it.
Wondering how they can do tunnels economically? They talk about it.
The starting point of the discussions about using tunnels should be based on the claims they have there, not worries that have already been addressed...
I personally do not see how any surface based approach can possibly cost less than the tunnel approach or be put in as quickly given the huge amount of problems it takes to put in a new rail line over long existing areas.

Re:Even More Simple
Nonetheless, I wouldn't be surprised if a hyperloop from SF to SD cost close to 100 billion, since it hasn't been done before, and a regular railroad running through a tunnel can cost more than $100,000,000 per mile.
Tunnel costs are proportional to tunnel cross sectional area - the hyperloops are designed to have greatly reduced cross sectional area compared to traditional train tunnels.
Also tunnel costs are proportional to boring time, Musk is reengineering the TBM (tunnel boring machine) for dramatically faster boring.
