In order to avoid wasting precious time on congested roads, Kobe chose to travel by helicopter, but the world is unstable, the great athlete was killed in an unfortunate accident, and the tragic lessons once again warned the rich that the aircraft is not necessarily the safest way to travel . p>
How to ensure safety and efficient commuting as much as possible, Musk opened his mind three years ago to dig a tunnel under the city for autonomous Tesla electric vehicles. p>
This full-time digging company is named “Boring”, one can be translated as drilling, the other is boring, and Chinese who is not familiar with Musk is also a good pun. p>
p>
In August 2019, the Las Vegas Convention and Tourism Board approved a contract with Boring to design and build a Loop system for the Las Vegas Convention Center to connect Las Vegas’ conventions and exhibitions. District and University campus area, Musk therefore won this order worth 48.7 million US dollars, losing in the bid is the local classic transportation scheme-monorail. p>
Following the experimental “test run” last year, Musk’s “boring move” has finally achieved staged results. Under the underground of the Las Vegas Convention and Exhibition Park, a 1600-meter tunnel was successfully opened, and only three months have passed since the formal start of this area. Its digging speed is not inferior to the construction of the Shanghai Tesla factory, which is another record in the history of tunneling. p>
p>
Different from the huge track of the subway, according to the pictures and video materials, the diameter of the Boring tunnel is not large. Almost only one Model X is more than the width. It can be imagined that the difficulty of excavation cannot be compared with the subway. p>
p>
Officials also said that the cost of tunnel excavation will not be very high. Under the same length of line, it is only one-tenth of the cost of subway tunnel excavation, or even about one-third. p>
After the tunnel is opened to traffic, those who come to Las Vegas to participate in the exhibition can ride Tesla for free and pass the Las Vegas Convention and Exhibition Park in more than 1 minute. According to Tesla’s plan, by January 2021, the Loop system can transport 4,400 attendees per hour. p>
Briefly explain the working logic of the Loop system: passengers descend vertically into the tunnel through the pod through the ground station. This vehicle is still a mass production model of Tesla. It may be a model based on the Model 3 chassis in the future.The “capsule electric car” can carry 8-16 people. Although the carrying capacity is still not as good as that of subway trains, its maximum speed can reach 250 kilometers per hour, which can completely compensate for its speed. p>

In 2018, Tesla dug an experimental tunnel in the backyard of California’s SpaceX Company and successfully carried out a real vehicle test. They installed four model-like four-wheel guide wheels on the front and rear of a Model X. , Without the “tray” previously conceived, vehicles driving in the tunnel rely on their own driving force. p>
First of all, the vehicle needs to have the ability to drive autonomously. It can control the brake throttle and direction by itself. The guide wheels are located between the body and the shoulder of the road to provide steering support for the vehicle. We can currently see that the road inside the tunnel is concrete, but the official said that the ground will be extremely smooth in the later stage, and the small friction will allow the car to drive fast enough. At the test site, the maximum speed of the vehicle reached 64 kilometers per hour. p>
p>
In a competition between the ground and the underground in 2019, the Model 3 in the tunnel ran at a maximum speed of 204.39 kilometers per hour, with up and down transmission and tunnel driving. The underground car completed 1.83 in 1 minute and 36 seconds. Kilometers of road, while ground vehicles took 3 minutes and 8 seconds. p>
Although the test is exciting, there is constant skepticism. For example, will up and down transmission cause ground congestion? The capacity of a car is too small; safety needs to be verified and so on … p>
In any case, Musk ’s crazy brain has once again entered reality and achieved commercialization and phased results. Whether this solution can alleviate traffic pressure and benefit people ’s livelihood, we will see at CES next year answer. p>
