I think we should accept that, at least in the case of the US, most future transit infrastructure will be built on existing roads. Every other options is an order of magnitude more expensive. Plus, we have so many roads! If we didn't use them it the most inefficient way possible - cramming them full of giants cars for single people who also happen to be terrible pilots - we could get a ton of bandwidth out of them. A…
I’ve slowly lost my innocence when it comes to public transportation in the US. At this point I can see that 95% of the country is absolutely locked into low-density single occupancy transportation at least till we invent sky cars. We have trillions in sunk cost that covers nearly every road, every home and every business in America. We will never, ever be Europe.

The Channel Tunnel was attempted in the 1800s and failed. A hundred years later they tried again and succeeded. So...
Apples and oranges false equivocation of vastly different engineering problems. The problem with vacuum trains is they aren't workable with current materials, are impractical, and are too damn expensive. https://youtu.be/RNFesa01llk
Of course, reversed stupidity is not intelligence, this isn't evidence that hyperloop is good, just a suggestion to choose a better source for your arguments.

#293There is a world where we dig tunnels under federal highways, and stick freight trucks down there. They'd run on a monorail, at 120+ mph. Surface vehicles would be dramatically limited in terms of height, width, and length. Maybe people buses could go down there? In my imagination these tunnels are, like, 200' down. Like mole people.
Why do people keep trying to invent more expensive, less traffic dense railroads. Did they stop teaching arithmetic in school?
Being intelligent yet humble isn't mutually exclusive, but I see a lot of elitism in that 'oh I have this concept which must be totally novel and I'm gonna implement it now' with engineering at large before we all start laughing at their inevitable failures from things they could have learned in the past. Crypto is cool, even cryptocurrency. 99.9% of people in the space though have no idea what they're doing with it. I still think it could be useful for voting and/or DNS for distributed consensus, the cryptocurrency aspect could be improved and already is a better backend imo than our batched out wire transfers with traditional banking (but it lags well behind credit cards or cash for point of sale transactions), and hell merkel trees are supremely useful already for supply chain or ex version control, but the hype and path of crypto currencies is an embarrassment in light of history.
Recent examples:
- mastodon and the fediverse in relation to the threads backlash
- cryptocurrency markets and the desire for regulation for when things go wrong (someone stole my coinz! My smart contract was exploited! My exchange was hacked! Fraud!)... Like it was speed running what the Netherlands+UK+us faced over 400 years in a period of 4 years
- any libertarian when they start to run their own government (sorry grandpa)

I guess you’re supposed to reenact the space whale scene from treasure planet.
An absolute gem of a movie. Didn't see it until I had kids and it was one of the few movies that I didn't get tired of rewatching again and again with them.

Contrarian take, but tons of truck traffic on interstate highways makes driving far more fun (as long as there isn't road maintenance or undue stoppage). I'm actually looking forward to future me being able to ride my motorcycle around a freight-train's worth of semi-automated cargo-haulers on interstates that are mostly devoid of vacationing families.
To each their own, but as a fellow motorcycle rider myself, I absolutely shit myself around huge trucks that won't be able to even see me.

Roads safe for cycling is half the battle. The other half is around zoning and mixing residential with businesses.
Legalize biking on the sidewalk nationwide. I don’t want to bike on the road for any reason. Bikers have far far lower chances of hurting pedestrians than cars do of bikers.

Why go underground (expensive 3rd dimension down) when we have the whole 3rd dimension up almost unused? The freight can be trucked by large Zeppelins for example (and electric at that with the most of the energy generated by the solar panels covering the upper surface of the Zeppelin https://news.ycombinator.com/item?id=38017937 ). The issues are pure engineering ones. These freight Zeppelins can be fully automated,…
A train car carries about a kiloton of cargo. How many zeppelins would that take? Edit: Actually, I can't count. Only a few hundred thousand pounds. That's still probably a bunch of zeppelinworths though.
Design the Zeppelin for literal tons of ballast, trade out sandbags/dirtbags for product or waste on docking, andaybe add an aerodynamic shield if you don't care about speed as much
We already sacrifice significant speed for boats, but I grant they're several orders of magnitude better at balancing buoyancy with cargo given they flot in the water rather than atmosphere

Seattle has some underground light rail tunnels that are shared with buses
Less now that I've moved out of premiere on line, but still

That sounds like railroads but worse. What's the advantage? Tunneling is incredibly expensive to do, yet you're proposing it in a situation where it'd need enough coverage so as to ban large freight transport over roads.
- no impact on environment, birds, bugs, animals, trees, etc...
- can use surface land for other things
- no weather exposure

The problem is the disparity of speed between travelers, same as for a highway. Pedestrians appear suddenly or don't know about your sudden appearance or intended motions, and pain or injury results.
