Do you tell your coworkers what to do if you pass out driving them to lunch? What if the one up front can't drive, what happens to the folks in the back seat?
I never had a buddy tell me what to do riding on his motorcycle if he had a problem.
Suppose I'm out fishing, riding in the now of the boat, and the one at the helm falls over (but not overboard). How many boaters provide instructions for this?
"Thanks for riding with me in my <whatever>. Just in case I faint, pass out or have a heart attack, this is what you should do . . ." Give me a speech like that, I wouldn't even get on a skateboard with you. Ever. No thanks, I'll just hitchhike home, it's got to be safer.
I tell people how to work the seatbelt, that one in a million idiot who can't figure it out, and where the air vents and heat are, as well as how to adjust the seats. Then I tell them to not touch the controls and watch their feet. That's about it.
