Steve Wozniak—aka "The Woz"—the investor, engineer, tech entrepreneur and philanthropist who co-founded Apple Inc. (AAPL) alongside Steve Jobs, says he no longer believes anything Tesla Inc. (TSLA) or its CEO Elon Musk says. 

While Woz still loves driving his Tesla, he spoke at the Nordic Business Forum in Stockholm regarding his frustration with the company's broken promises regarding its technology, suggesting that Musk stop overhyping its self-driving technology. 

"Now I don't believe anything Elon Musk or Tesla says, but I still love the car," said the tech pioneer, who owns two Model S sedans. Wozniak accused the Palo Alto, Calif.-based electric car company of using "cheap" strategies to deflect responsibility for mistakes.

"Our first Tesla slid off some ice late at night up at Lake Tahoe, and we ended up in a snow bank," said Wozniak in a Q&A session at the conference. "There was no damage, but it was clear we needed a four-wheel-drive Tesla." The Apple co-founder referred to his decision to upgrade his electric vehicle, back when he believed in Musk's promise made in October 2016 that Tesla Model 3 cars would be able to drive themselves through cities and highways by the end of 2017. 

After years of upgrades and new sensors, Woz sees Tesla as a company that has made major promises and delivered well under the bar. "I love that car, but the trouble is Elon Musk is portrayed in a lot of moves with a lack of faith and trust," he said. "What he says, can you really believe in him? Is he just a good salesman, like Jobs, and may not be there [in the end]?"

Wozniak went as far as to suggest that "every other car manufacturer in the world," including Audi and BMW, "are actually ahead of Tesla for self-driving cars." He then praised his Chevy Bolt EV, which he prefers to drive for everyday life. (See also: Alibaba Invests in Chinese Electric Carmaker.)
