People still think Boring Company is just about infrastructure? Big mistake. Check out their tunnel operation data from Las Vegas and Dubai in 2026—this is actually Tesla FSD's 'clean lab.' On public roads, autonomous driving has to deal with countless complex random variables. But in Boring Company's underground closed-loop tunnels, the system can achieve 100% controllability. The 2026 data shows that vehicle traffic efficiency inside the tunnels is 3 times higher than traditional roadways. What Musk is building is a 'physical firewall' specifically designed to implement his most aggressive autonomous driving plans. If you don’t get this logic, you won’t understand where Tesla’s real ceiling lies.
