After promising fully self driving cars for over half a decade, Musk still isn't giving up hope.

During the company's earnings call on Wednesday, Musk promised to have a dedicatedrobotaxi with no steering wheel.

He said during the call that it would be a massive achievement to achieve the lowest cost per mile, cost per kilometer and accounting everything.

Musk said that the vehicle wouldn't have a steering wheel or pedals.

It's not clear whether investors will allow anything like that. After all, self-driving technologies have turned out to be a big problem for the billionaire CEO, who has faced a lot of attention and scrutiny from US regulators in trying to bring them to market.

Mr. Robotaxi

At the company's Cyber Rodeo event earlier this month, Musk teased a new car that was dedicated to him.

Massive scale. He said at the event that there would be a dedicated robot taxi.

Musk said that the vehicles would feature afuturistic design.

If the car company didn't get to the point this year when full self driving becomes safer than humans driving, Musk would be shocked.

In the long run, Musk still believes that humanoid robots like the one Musk is working on will be an even bigger success than robotaxis.

He said during Wednesday's call that theOptimus will be worth more than the car business.

The company hasn't shown its cards when it comes to the new humanoid robot assistant. The only thing we have seen so far is a human performer in a costume.

Musk says he wants to make a car with no steering wheel or pedals.

There are reports that workers were forced to sleep on the factory floor.
