You know what? This idea makes actual sense.

I do think we should still spend money on upgrading roads but a balanced transportation system makes sense. Germany manages to have the world-famous Autobahn and a better transit network than America.

Parts of the US have density, like the Northeast, California, Florida, the PNW, and the Texas Triangle. We don't need high speed rail between Rapid City and Bismarck.

And yet the HSR line here has a whole bunch of stops planned for non-dense areas.  That corridor should have directed lined between Los Angeles and San Francisco as a proof of concept.

Another thing that hurts the appeal of HSR: American airports are more conveniently located and better connected than their counterparts abroad.

Airport security is still an issue though and takes a few hours. There's a reason why acela is so good.

the cahsr was bungled I won't disagree with you on that.

If everyone got tsa precheck the benefits would cancel out. Many don't travel enough for it to be worth it.

That's not true, Precheck is less stringent (they don't make you take your shoes off for instance) and so it takes them less time to process each person.

if you take amtrak to new york you end up in midtown. You fly it can be a pain to get there.

Where are the AI airport security robots?  All this time spent on 150 MPH AI cars and not one suggestion about sentient security bots seems off to me.

Beware, they just marked you as a high risk person for wanting to destroy a lot of union jobs.

Tell they that I'll be waiting in the Wendy's parking lot with my TSA robot goon squad.

If ai took over the tsa I'm never flying again. I don't trust ai to keep airplanes safe.

I think armed autonomous drones are far off.

But one interesting thing would be remotely controlled robots *on planes* that would allow air marshalls to be in multiple places at once.

When I first saw the thread title I thought it was "8,000 miles per hour per lane on the highways of tomorrow".

It's a K12 thread though, so it could be believable.

8,000 cars per hour going 8,000 miles per hour. Is that possible under Newtonian physics?

Until one needs to stop, probably.

Why stop with Newtonian physics though? Imagine how fast point A to point B is an Einstein-Rosen Bridge?

Might not look into the failure rate of TSA screeners during their own tests.

This study says that freeway lanes for autonomous cars could carry up to *12,000* vehicles per hour.

I think 25 thousand is a better number. It looks nicer, and is equally realistic

Everything needs some kind of manual backup. Yes, the planes actually CAN fly themselves for the most part, but you still need a pilot as a backup. You always will. It's the same reason you can't fall asleep behind the wheel of your Tesla.

It's like the old Jurassic Park issue. Automation is great, but what happens if/when it fails and you've got no manual backups? Just because your automation works, doesn't mean the car next to you does. Since I've had my Subaru, which uses adaptive cruise control, I've found I am still overriding it a lot. Not because it doesn't work, but because it works too well: it will stop so suddenly it can be really jerky. I've found doing a manual override lets me get a smoother slowdown, and it will still always apply an emergency break anyway to prevent a crash.

As I said earlier in this thread, my takeaway is that all this stuff is cool in theory, but I'll believe it when it happens. Not to mention we can't even agree on what the "highway of tomorrow" will be. Remember the experiment of putting solar panels on them and having cars drive over them to generate electricity? It didn't work out in practice. Will "highways of tomorrow" be fully computer controlled like what we saw in "Minority Report," and thus be overridden if/when the powers that be end up not liking you or think you've done something wrong? What if I want to take a scenic route, but my smart car only lets me go the most optimal route?
