Not sure I understand you...for reference's sake, here's the location:

How direct of a path you take from the offramp depends on the signage, it's not unreasonable to think that the writer missed it.
And when you say: "Even with that ridiculous path it's only 0.5 miles."...you did read the OP right?
Musk uses this chart in which he says the reporter "circled" around for 0.6 miles:

0.6 is very close to 0.5. This doesn't prove the reporter didn't do something nefarious...but the line between accidentally and purposefully taking a circuitous route here is not a wide margin.
I mean, if the reporter wanted to screw with Tesla -- and while ostensibly being unaware that he was tracked -- why wouldn't he just miss his exit a couple of times and get stranded on the side of the freeway? If you wanted maximum damning effect, that's what I would go for...driving around a McDonalds seems less efficient.
