Elon Musk's companies, SpaceX and Tesla, are well renowned for their innovations in environmentally friendly vehicles and in SpaceX's case long-term plans to migrate the human race to Mars.

But Musk, with his bizarre tweets and business plans (including one that basically turns a human colony on Mars into a debtor's prison) is not always the most popular person.

And for one of his most recent projects, he's getting roasted hardcore.

The invention, which looks like a segment of Disney's Test Track, amounts to little more than a brief tunnel with LED lights that change color.

In the video, Kylie Jenner can be heard saying "this is crazy!" as the car drives her through the invention, but Twitter can't help but both laugh and be perplexed at the same time.

The Boring Company, one of Musk's other business endeavors responsible for this project, constructed this tunnel for one mile under the Las Vegas strip.

It costs $5 to drive through the tunnel.

While some people can't help but laugh at the ridiculousness of this promotion, others are citing safety concerns.

Musk claimed construction of such tunnels will cut driving times across the nation. In 2017, Musk bragged he'd received US government approval to construct a tunnel from New York City to Washington, DC which would supposedly cut driving time down to 30 minutes.

This project has yet to materialize.

The USA's dependence on cars has become apparent in its infrastructure projects throughout the years, though growing pressure mounts on the current federal government to invest more in public transit, such as high speed rail lines.

Maybe these LED tunnels will become subways of the future.
