Musk founded Boring, an underground tunneling company, in 2017 and has managed to make a valuable investment. Recently, overseas media reported that Musk believes that the underground transportation system only applies to electric vehicles, after all, the tunnel fuel vehicle emissions may be a problem. “The urban underground tunnel system only applies to pure electric vehicles with zero emissions, because there is no exhaust gas that is key,” Mr Musk said. “
Media speculated that if the tunnel was designed to be suitable for all vehicles, the new wind system that discharges exhaust gas could significantly increase its construction costs.
Musk recently tweeted that an underground transportation tunnel being built in Las Vegas is expected to open next year as an alternative to reducing urban traffic congestion.
It is reported that the project will consist of two tunnels, each about 1 mile (1.6 km) long, with a top speed of 250 km/h.
