what happens if people decide to open their windows in the tunnel? does the drag slowdown the car?
what if they start throwing out garbage, or worse, glass and puncture the tires of the following vehicle?
anyway... took me a while to get through everything mentioned and written in this thread... and so many comments to pick from...
A high capacity train is great for situations like taking people downtown to work during rush hour or for sporting events but it doesn't work for other daily uses. [...]
Have you EVER rode a subway outside of rushhour? or left the US?
That mass transit only works because the density and because they have built the city with with it in mind for a century. Most cities in the US are too far gone.
Many European Cities built their public transport networks long AFTER the US had demolished theirs. So I call bullshit on your argument.
The US has the best prerequisits for public transport: space.
Doesn't matter how straight forward it is to use, if it doesn't take you where you need to go in a reasonable amount of time people won't use it. [...]
so... your solution is to just build even less useful infrastructure for people to not use then?
I just threw a couple pins down in Columbus and it said 16 min by car and 1 hour by transit. That is why people don't take transit in it's current form.
but instead of improving it... you suggest to put all our faith in something that makes no sense right out of the gate
The innovation here is cost. That's always been musks bread and butter, taking things that have historically been prohibitively expensive to the point where it stalls any and all innovation or funding resulting in industries that have been completely stagnant for decades, and finding new ways to make them exponentially cheaper by using physics first principles and starting from scratch. While attempting this can come up with new engineering solutions in the process that sometimes can revolutionize the entire field see: SpaceX
[...]These tunnels can go to less dense areas because they are cheaper to build.[...]
That it is cheap to build so it can actually be built rather than just discussed on message boards like these other ideas.
where does the cheaper to build claim come from?
Have you even read the article you're linking to? nothing there suggests Musk building cheaper, he isn't even mention. It just says that Europe builds at a fraction of the cost as the US. And that has NOTHING to do with what dear Elon does.

Expanding highways isn't working. Mass transit isn't wanted. So what's the solution?
you know... like better mass transit?
Because "Mass transit isn't wanted" is a claim backed-up by nothing. Or rather, the exact opposite of what pretty much every study ever on the issue suggests.
[...] If you read a little of the history of the 20th century you would notice the dominance of cars is in no small part due to the oil and automobile industries having an immense amount of power in determining public policy.
It's kind of ironic how our two favourite shills always accuse others of being in bed with big oil, yet cling to the same rhetoric when defending their master. This stupid tunnel isn't doing anything except for cementing the status-quo for private car use. Next they're going to tell us how it's great for the environment
4000 vehicles/hour at 155mph (250km/h)
So that's 4000 vehicles in a 250km length of tunnel, or 16 per km or 62.5m headway
Will require an emergency braking of ~4G (assuming perfect reaction/signalling time). Comfy.
shh! don't you dare bring actual science into this. Can't have that in a Musk thread or Musk related topic. God knows he wouldn't bother with this stuff. He just wills it into existence
