An arrow on the sidewall that the driver may or may not notice, and that she probably doesn’t know exists to begin with has nothing to do with a pre-trip inspection. Even if she went by the letter of her owner’s manual’s description of a pre-trip inspection, I doubt it
would say anything about checking to make sure that, in the event the owner had recently had directional tires installed on the vehicle, that she should make sure they were installed correctly. Of course, from this day on, you could take her to task if she got another set of directional tires and didn’t check to see if they were installed properly.
I’m not sure what the gist of the rest of your post is but I would be glad to answer the questions you asked:
‘What do you mean by “non automotive person”?’
No offense, but this seems so obvious that it’s hard to put it into words. I guess it’s a subjective call, but one meaning might be, a person who, though knowledgeable about certain superficial aspects of their automobile, has never worked on a car and may have only a foggy grasp, at best, concerning the fundamentals of automotive theory.
“You do drive a car, don’t you?”
Yes.
“You are capable of conducting a routine pre-trip inspection, which should include inspecting your tires, checking the fluids, adjusting the mirrors, etc., right?”
Yes.
“I should hope a car is more to you than just an appliance you get into and drive without personally making sure it is safe.”
I’ll try to answer your implied question here.
As an inspection mechanic, yes, I treat my car as more than an appliance. However, I often do get in it and drive it without personally making sure it’s safe. However, periodically I
check all kinds of safety related things on it.
“Did you take a Driver’s Education class before you got your license?”
No, I got my license off a crackerjack box. (It’s a joke!) Sorry, Whitey; yes, in the summer of 67. I hadn’t even heard of hippies yet.
“Were you there the day they discussed pre-trip inspections?”
Wow, this is dirty pool! You’re asking me to dredge something out of my memory from 42 years ago! Well, I don’t remember getting sick that summer–I usually only get sick in the winter–so yeah, I probably was there that day, but I can’t say for sure.
I do have intense memories of some things, though. The seniors, that had just graduated, had taken a 55 gallon drum, painted it to look like a Colt 45 Malt Liquor can, and had hoisted it on top of the gymnasium roof. It overlooked the area where we practiced parallel parking. They had written “Jack’s Favorite” on it. Jack Livingston was the principal.
Watch out for those directional tires, Whitey.
