Proposition (held fixed): Would The Boring Company build an NY–Philadelphia–Baltimore–DC Hyperloop with NY–DC in 29 minutes, and a high-speed Loop from downtown Chicago to O’Hare? Broader tunnel history is on the Hyperloop and Boring Company page.

From verbal approval for NY–DC in 29 minutes to “Permits were impossible to get” — with working tunnels in Las Vegas.

What did not change: tunnels as the stated fix for city traffic · a Hyperloop as a later, faster step · permits as the gate Elon named. ElonsFAQ corpus · verified 2026-10-23 · unofficial.
City of Chicago, not an Elon quote (14 Jun 2018 press release, Mayor Emanuel Announces Company Selected… · Single source for the 12-minute figure): the city said The Boring Company planned to deliver about 12-minute service from downtown Block 37 to O’Hare on electric vehicles in twin underground tunnels, with no taxpayer subsidy.
22 October 2018, on X, about the Hawthorne demo tunnel:
“This is a ~ 6000 ft demo tunnel. First operational, high-speed tunnel still set for Chicago, pending regulatory approvals.”
Company figures, not Elon quotes (Vegas Loop project page · Single source, retrieved 28 Oct 2026): Vegas Loop has transported more than 4 million passengers through 14 stations, with transit times between 2 and 8 minutes; Clark County and the City of Las Vegas have approved 68 miles of tunnel and 123 stations. The page lists Vegas Loop as the operating public system. This record has no operating NY–DC Hyperloop, Chicago O’Hare Loop, or LA Dugout Loop.

Neutral conclusion
On 20 Jul 2017 Elon wrote that The Boring Company had verbal government approval for an underground NY–Phil–Balt–DC Hyperloop, NY–DC in 29 minutes, city center to city center, with formal approval still needed but expected rapidly, and that Chicago had already approached the company about O’Hare to downtown. In Nov 2017 he said the company would compete to fund, build and operate that Chicago Loop; in Oct 2018 the first operational high-speed tunnel was “still set for Chicago”. The 12-minute downtown-to-O’Hare figure is the City of Chicago’s, from 14 Jun 2018. In May 2025 Elon pointed to working tunnels in Las Vegas as the proof of concept. In Oct 2026, asked what happened to NY–DC, he wrote that permits were impossible to get. Vegas Loop is the operating public system on The Boring Company’s own page. This compares dated wording; it makes no claim about motives.
Scope
Indexed ElonsFAQ corpus (transcripts and X posts); not every Elon Musk interview.
YouTube wording is from automatic captions (ASR); fillers such as “uh” are kept as spoken.
Calendar readings of relative dates (next year, this year, in 2 years) use the statement date.
Latest Tesla and SpaceX operating items are company statements, not Elon quotes, and are labeled.
