“As a Tesla owner, a 47-year-old male recovering from Covid-19, and someone very concerned simultaneously about the environment, the economy, my kids’ and my parents’ future, this ain’t great,” said Jeff Guilfoyle, a product manager at FireEye in San Diego. “This disease is no joke, and the long-term health impacts are unknown for survivors.”

Many have implored Mr. Musk online to stop.

Raja Sohail Abbas, the chief executive of an outpatient psychiatric clinic in Allentown, Pa., wrote: “I am a Tesla owner and love the company. You have to stop being an idiot about this.”

“Tesla owner and Fan here, but this was a disappointing tweet despite the frustrations of and holdups,” added Alex Goodchild, a D.J. in Brooklyn. “Words are weapons especially when used during situations like the one we’re currently experiencing. You sound just like Trump in this tweet.”

The debate has riven the Tesla community.
