“Not as much as tunnels though”

“26 ft diameter tunnel running 2 miles under D.C. https://t.co/XFQkioEsg8”

“@shaunmmaguire The throughout in the Vegas tunnels is already better than an average subway btw. It’s a myth that subways are super efficient.”

“Upgraded SpaceX/Tesla Hyperloop pod speed test soon. Will try to reach half speed of sound (and brake) within ~1.2km.”

“Hyperloop Alpha at http://t.co/ZRTcT2b8bP and http://t.co/7cucKKprPB http://t.co/LYhuRxUntA http://spacex.com/hyperloop”

“@BillyM2k We are changing the auto-reply from 💩 to a “We will get back to you soon” infinite loop”

“Will be building a Hyperloop test track for companies and student teams to test out their pods. Most likely in Texas.”

“This time, the vacuum tunnel will be a bit longer & SpaceX will provide some advance funding for student teams with most promising designs. Bonus award for all race pods that exceed half the speed of sound!”

“@tobi It’s a game-changer. Buildings are 3D, which requires transport to be 3D to solve congestion. Many layers of tunnels underground to impedance match to the many floors of buildings above ground.”

“That special hat delivery will take place deep within the real, but fictional (of course), tunnel we are building under LA while you drive the giant machine blindfolded. This will actually happen.”

“Imma gonna dig that tunnel with this here hammer”

“Congratulations to WARR team from Tech Univ Munich for winning 2nd @Hyperloop competition! Peak speed of 324 km/h, which is over 200 mph!!”

“@2AvSagas I guess you could say it’s a 150 mph, underground, autonomous, electric bus that automatically switches between tunnels and lifts. So, yes, a bus.”

“Just arrived at the @Hyperloop competition final. Student teams have amazing talent!”

“@ikristoph @brickroad7 Team is closing the loop on interventions very rapidly. To get enough training examples for potential serious accidents, we have to run them in sim, as we have so few in the fleet, despite doing ~1M miles per day of FSD.”

“@PeterDiamandis Total miles traveled will increase significantly when people don’t have to drive themselves in soil-destroying traffic. The resulting traffic increase will slow transit times, even with autonomous cars. That’s why we will need a network of multi-level tunnels, which can… https://t.co/154llN6r3D https://x.com/i/web/status/2022422853094916496”

“@jacobinmag Btw, if anyone else wants to build this tunnel, please do so. It’s a lot of work.”

“Btw, 99% likely to be fine (closed loop TVC wd overcome error), but that 1% chance isn't worth rolling the dice. Better to wait a day.”

“@UniverCurious High time we had tunnels!”

“@jonbbc @WholeMarsBlog @aelluswamy 10.69.1 is even better. We reduced latency & jitter in hardware command loop, so time from object detection to brake actuation is 10% to 20% better.”

“Tesla owner drives through a flooded tunnel & out the other side https://t.co/RmPxdZShhq http://electrek.co/2016/06/18/tesla-model-s-driving-swimming-flooded-tunnel-video/”

“@rainnwilson Your Tesla can function as a boat for brief periods of time https://t.co/FONhnIiv8j https://electrek.co/2016/06/18/tesla-model-s-driving-swimming-flooded-tunnel-video/”

“@PopMech Tunnels ftw”

“@bscholl There has to be an effective feedback loop to the people or we live in rule of the bureau, not rule of the people (demos)”

“@alexxubyte Twitter search will add feedback loops to improve result rank based on which result you click on & whether you immediately click back (implies wrong result)”

“@TEDTalks @i_firth Norway has some really cool tunnels and bridges”

“@Teslaconomics Tunnels solve traffic”

“@EdKrassen Close the massive “anyone can have asylum for no reason” loophole”

“@WholeMarsBlog Tunneled under the road from one property to another. This is to test the new machine.”

“@MinimalDuck @Tesla @Gfilche @WholeMarsBlog Tunnels …”

“Will publish Hyperloop alpha design by Aug 12. Critical feedback for improvements would be much appreciated.”

“@Vernon3Austin I love trains, but the future is individualized mass transit with autonomous electric vehicles taking you precisely to your destination. Tunnels are needed to address the fundamental choke points in cities. You can’t have 3D buildings and expect a 2D transport system to be”

“@ajtourville Important to note that we also use the Tesla HW4 AI computer in the training loop with Nvidia GPUs, currently at roughly a 1:2 ratio. Also, we’re changing the name from Hardware 4 (HW4) to Artificial Intelligence 4 (AI4). That means ~90k H100, plus ~40k AI4 computers.”

“Promising conversations with @MayorOfLA regarding tunnel network that would carry cars, bikes & pedestrians. Permits harder than technology. https://t.co/0dxrXBOOWy https://x.com/abc7adrienne/status/876114755169079296”

“According to experts, Hyperloop is both obvious and impossible. Maybe pick one or the other? https://t.co/JkRWd0lFS8 http://nymag.com/selectall/2016/10/the-kink-in-elon-musks-hyperloop.html”

“@Erdayastronaut @KlotzAdam @NASASpaceflight We’ve tested a sub-scale version in a wind tunnel with active aero closing the loop for stability, so it will probably work at scale, but reality tends to bite you on the ass”

“Pulled all nighter working on Hyperloop (as did others). Hopefully not too many mistakes. Will publish link at 1:30 PDT.”

“@MissTrade Already started DC to NY route. Hopefully start LA to SF next year. That will be true @Hyperloop w pressurized pods in near vacuum tunnels & faster than jetliner.”

“@erikbryn @ericschmidt @CondoleezzaRice @scsp_ai @Ukraine Hyperloop could do that trip in less than half an hour”

“@BillyM2k Or maybe a “Check with us again tomorrow” loop”

“@OfficeOfMike @DasaelR @QuintusActual @iamgingertrash These judges are breaking the feedback loop to the people and therefore subverting democracy itself”

“@IndianInterest Actually, Hyperloop draws a near vacuum in tube & each pod is powered w electric motors. It is opposite of pneumatically powered.”

“RT @Timcast: I worked as a fund raiser for several top NGOs Its all fake Lies, tricks, and legal loopholes to get money for nothing. We…”

“@Nigel_Lockyer @Penn @Fermilab If you ever want to build a long accelerator tunnel, straight or circular, I know some people …”

“@curiousworlds For sure. First set of tunnels are to alleviate greater LA urban congestion. Will start NY-DC in parallel. Then prob LA-SF and a TX loop.”

“@DrKnowItAll16 @Tesla_AI Yes, this is fully autonomous (no human in the loop anywhere)”

“@MattWalshBlog The “asylum seeker” loophole has been abused to an absurd degree”

“RT @jimmybajimmyba: we are seeing the loop of intelligence expansion and cost compression playing out for the last few years. this time, "t…”

“Right move is try both tunnels and flying cars. Otherwise, having 2D streets and 3D buildings means bad traffic forever.”

“Latest vertical landing rocket vid. 325M altitude, hold against wind, land w T/W>1, radar in loop http://t.co/I68Xxpb1EQ http://youtu.be/eGimzB5QM1M”
