Likely a mixture of these answers, though if you want to wait for an expert to weigh in maybe ask for that. A roadway is obviously a very different environment with a lot of money and research put into ensuring it can handle a lot of traffic and weight, having to accommodate worst case scenarios so it’s obviously going to have a very strong base, and a comparitively very durable and thick base of asphalt. Your driveway, on the other hand, is probably going to be covered in a mixture very much driven by price. If you do the minimum underlayment and thickness, you’re probably going to need to give it every advantage possible to avoid rework.

Pretty sure that was the joke. I don’t know how they can lie about the height of someone who must certainly be one of the most photographed people in the world (POTUS, I mean, why in the world anyone would want to photograph Trump himself is beyond me), but pretty sure even that one is wrong. The others are much easier to lie about, even if they are obviously wrong.
