The title here matches the original title of the article, but I have to say: what is with the comma between subject and predicate in a sentence?

Ex. Mary, eats a pie.

"Tesla delays [and] reduces": the comma is used as an "and" (common in American titles, https://en.wikipedia.org/wiki/Comma_splice)

The comma seems completely fine?

Your example is not the same construction, "Mary turns off the oven, eats a pie" is a more similar type of phrasal construction.

I somehow misread. No more commenting for me before coffee.
