Elon Musk’s high-speed LA tunnels rely on technique used by roller coasters 100 years ago.

The technology behind Elon Musk’s plan to beat Los Angeles traffic using high-speed underground ‘skates’ may tap into an outdated method seen in vintage roller coasters. After the unveiling event earlier this month to show off the mile-long stretch of LA’s first tunnel, some engineers have pointed out that it bears semblance to the side-friction roller coasters that were largely phased out starting in the early 1900s. Experts say achieving stability at high speeds in such a system would be a challenge, and the sideways motion it relies on could make for a nausea-inducing ride, according to DYPR News. Sc
