Tesla has reportedly asked its Model 3 factory workers to prove the “haters” wrong by stepping up car production. In a memo obtained by Bloomberg, Tesla engineering chief Doug Field told staff it would be an “incredible victory” to exceed the production of 300 Model 3 vehicles a day. Field’s memo, reportedly sent on March 23, expressed feeling insulted by people doubting Tesla’s ability to hit its production targets. “Let’s make them regret ever betting against us,” Field wrote.
