You would have thought the author of this article had pissed in everyone's cereal.
There's no way you should be able to click enough buttons in a car to be automatically billed $14k without seeing at least one prompt that says something like:
"You're requesting 'feature X' to be installed. Do you understand that we're immediately going to charge you $14k?"
...and then requiring some sort of PIN or password to confirm. It doesn't matter that they reversed the charges.
Also, they can call it "Full Self Driving," but that doesn't mean the car actually drives itself or that it's a good idea to use it or that it's safe. I'm honestly shocked that they haven't been charged with fraud.
