Elon Musk: "Santa Monica to Westwood in Five Minutes."

Elon Musk, our century's version of Leonardo da Vinci, has posted on his Instagram page a video of his electronic underground sled to move automobiles. The Tesla founder and CEO has also begun to bore tunnels near his company's Hawthorne headquarters.

Musk posted a demonstration of one of the car-carrying electric sleds on his Instagram page. In theory, these sleds would accelerate down a network of subterranean tunnels at about 125 mph, and automatically switching from one tunnel to the next.

"Would mean Santa Monica to Westwood in 5 minutes," Musk posted with the picture. The current travel time from Santa Monica to Westwood is about 20 minutes.

He is the founder, CEO, and CTO of SpaceX; co-founder, CEO, and product architect of Tesla Inc.; founder and CEO of Neuralink; co-founder and chairman of SolarCity; co-chairman of OpenAI; co-founder of Zip2; and founder of X.com, which merged with Confinity and took the name PayPal.

As of May 2017, he has an estimated net worth of $15.2 billion, making him the 80th-wealthiest person in the world. In December 2016, Musk was ranked 21st on Forbes list of The World's Most Powerful People.

Musk has stated that the goals of SolarCity, Tesla, and SpaceX revolve around his vision to change the world and humanity. His goals include reducing global warming through sustainable energy production and consumption, and reducing the "risk of human extinction" by "making life multiplanetary" by establishing a human colony on Mars.

In addition to his primary business pursuits, he has also envisioned a high-speed transportation system known as the Hyperloop, and has proposed a VTOL supersonic jet aircraft with electric fan propulsion, known as the Musk electric jet.
